        1. Notation text is divided up into lines separated by line terminators. A line terminator may be a single character (such as a line feed) or a sequence of characters (such as a carriage return/line feed combination). This specification does not require any specific encoding for a line terminator, but any encoding used must be consistent throughout any specific input text.
        2. Any characters in text line that are not a part of the line terminator are referred to as line text.
        3. A white space character is a space, tab, form feed or line terminator. Any contiguous sequence of white space characters can be used to separate tokens that would otherwise be considered to be part of a single token. It is otherwise ignored, with the single exception that a line terminator is used to mark the end of a single-line note (see 8.2.2.2).

        1. A root Namespace is a Namespace that has no owningNamespace (see 8.3.2.4). Every Element other than a root Namespace must be contained, directly or indirectly, within some root Namespace. Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
        2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
        3. A qualified name is notated as a sequence of segment names separated by \"::\" punctuation, optionally with the global scope qualifier \"$\" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

        1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
        2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
        3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        1. Notation text is divided up into lines separated by line terminators. A line terminator may be a single character (such as a line feed) or a sequence of characters (such as a carriage return/line feed combination). This specification does not require any specific encoding for a line terminator, but any encoding used must be consistent throughout any specific input text.
          2. 
+// 
        2. Any characters in text line that are not a part of the line terminator are referred to as line text.
          3. 
+// 
        3. A white space character is a space, tab, form feed or line terminator. Any contiguous sequence of white space characters can be used to separate tokens that would otherwise be considered to be part of a single token. It is otherwise ignored, with the single exception that a line terminator is used to mark the end of a single-line note (see 8.2.2.2).

        1. A root Namespace is a Namespace that has no owningNamespace (see 8.3.2.4). Every Element other than a root Namespace must be contained, directly or indirectly, within some root Namespace. Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.

+// 
        2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
          3. 
+// 
        3. A qualified name is notated as a sequence of segment names separated by "::" punctuation, optionally with the global scope qualifier "$" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

        1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
          2. 
+// 
        2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
          3. 
+// 
        3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

For those cases in which the InvocationExpression is an OperatorExpression, its operator shall be resolved to the appropriate library function as given in Table 7. Note also that, for a CollectionExpression or SelectExpression, the abstract syntax constrains the operator to be collect and select, respectively, separately from the . and .? symbols used in their concrete syntax notation (see 8.3.4.8.2 and 8.3.4.8.18).

        2. The grammar allows a bracket syntax [...]that parses to an invocation of the library Function BaseFunctions::'[', as shown in Table 7. This notation is available for use with domain-specific library models that given a concrete definition to the abstract base '[' Function, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).

OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).

Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
+//   2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
+//   3. A qualified name is notated as a sequence of segment names separated by "::" punctuation, optionally with the global scope qualifier "$" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

+//   1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
+//   2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
+//   3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        1. A root Namespace is a Namespace that has no owningNamespace (see 8.3.2.4). Every Element other than a root Namespace must be contained, directly or indirectly, within some root Namespace. Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
        2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
        3. A qualified name is notated as a sequence of segment names separated by \"::\" punctuation, optionally with the global scope qualifier \"$\" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

        1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
        2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
        3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        1. Primary expressions provide additional shorthand notations for certain kinds of InvocationExpressions. For those cases in which the InvocationExpression is an OperatorExpression, its operator shall be resolved to the appropriate library function as given in Table 7. Note also that, for a CollectionExpression or SelectExpression, the abstract syntax constrains the operator to be collect and select, respectively, separately from the . and .? symbols used in their concrete syntax notation (see 8.3.4.8.2 and 8.3.4.8.18).
        2. The grammar allows a bracket syntax [...]that parses to an invocation of the library Function BaseFunctions::'[', as shown in Table 7. This notation is available for use with domain-specific library models that given a concrete definition to the abstract base '[' Function, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        3. A white space character is a space, tab, form feed or line terminator. Any contiguous sequence of white space characters can be used to separate tokens that would otherwise be considered to be part of a single token. It is otherwise ignored, with the single exception that a line terminator is used to mark the end of a single-line note (see 8.2.2.2).

        1. A root Namespace is a Namespace that has no owningNamespace (see 8.3.2.4). Every Element other than a root Namespace must be contained, directly or indirectly, within some root Namespace. Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
          2. 
+// 
        2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
          3. 
+// 
        3. A qualified name is notated as a sequence of segment names separated by "::" punctuation, optionally with the global scope qualifier "$" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

        1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
          2. 
+// 
        2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
          3. 
+// 
        3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        1. Primary expressions provide additional shorthand notations for certain kinds of InvocationExpressions. For those cases in which the InvocationExpression is an OperatorExpression, its operator shall be resolved to the appropriate library function as given in Table 7. Note also that, for a CollectionExpression or SelectExpression, the abstract syntax constrains the operator to be collect and select, respectively, separately from the . and .? symbols used in their concrete syntax notation (see 8.3.4.8.2 and 8.3.4.8.18).

An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

        1. // 1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
          2.

        2. // 2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
          3.

        3. // 3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
+//   2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
+//   3. A qualified name is notated as a sequence of segment names separated by "::" punctuation, optionally with the global scope qualifier "$" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

+//   1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
+//   2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
+//   3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

        1. Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
        2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
          • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
          • Append the name so constructed to the end of the entire original QualifiedName.
          For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

+// 
        1. Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
          2. 
+// 
        2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
+// 
            
+// 
          • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
            • 
+// 
          • Append the name so constructed to the end of the entire original QualifiedName.
          For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
+//   2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
+//     • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
+//     • Append the name so constructed to the end of the entire original QualifiedName.
+//   For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

        1. Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
        2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
          • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
          • Append the name so constructed to the end of the entire original QualifiedName.
          For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

+// 
        1. Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
          2. 
+// 
        2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
+// 
            
+// 
          • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
            • 
+// 
          • Append the name so constructed to the end of the entire original QualifiedName.
          For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
+//   2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
+//     • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
+//     • Append the name so constructed to the end of the entire original QualifiedName.
+//   For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].

A line terminator may be a single character (such as a line feed) or a sequence of characters (such as a carriage return/line feed combination). This specification does not require any specific encoding for a line terminator, but any encoding used must be consistent throughout any specific input text.
+  line_comment	//   2. Any characters in text line that are not a part of the line terminator are referred to as line text.
+  line_comment	//   3. A white space character is a space, tab, form feed or line terminator. Any contiguous sequence of white space characters can be used to separate tokens that would otherwise be considered to be part of a single token. It is otherwise ignored, with the single exception that a line terminator is used to mark the end of a single-line note (see 8.2.2.2).

Every Element other than a root Namespace must be contained, directly or indirectly, within some root Namespace. Therefore, every valid KerML concrete syntax text can be parsed starting from the RootNamespace production.
+  line_comment	//   2. PrefixMetadataMember is defined in the Kernel layer (see 8.2.5.12).
+  line_comment	//   3. A qualified name is notated as a sequence of segment names separated by "::" punctuation, optionally with the global scope qualifier "$" as an initial segment. An unqualified name can be considered the degenerate case of a qualified name with a single segment name. A qualified name is used in the KerML textual concrete syntax to identify an Element that is being referred to in the representation of another Element. A qualified name used in this way does not appear in the corresponding abstract syntax—instead, the abstract syntax representation contains an actual reference to the identified Element. Name resolution is the process of determining the Element that is identified by a qualified name. The segment names of the qualified name other than the last identify a sequence of nested Namespaces that provide the context for resolving the final segment name (see 8.2.3.5). The notation [QualifiedName] is used in concrete syntax grammar productions to indicate the result of resolving text parsed as a QualifiedName (see also 8.2.1).

+  line_comment	//   1. OperatorExpressions provide a shorthand notation for InvocationExpressions that invoke a library Function represented as an operator symbol. Table 5 shows the mapping from operator symbols to the Functions they represent from the Kernel Model Library (see Clause 9). An OperatorExpression contains subexpressions called its operands that generally correspond to the argument Expressions of the OperatorExpression, except in the case of operators representing control Functions, in which case the evaluation of certain operands is as determined by the Function (see 8.4.4.9 for details).
+  line_comment	//   2. Though not directly expressed in the syntactic productions given above, in any OperatorExpression containing nested OperatorExpressions, the nested OperatorExpressions shall be implicitly grouped according to the precedence of the operators involved, as given in Table 6. OperatorExpressions with higher precedence operators shall be grouped more tightly than those with lower precedence operators. Further, all BinaryOperators other than exponentiation are left-associative (i.e, they group to the left), while the exponentiation operators (^ and **) are right-associative (i.e., they group to the right).
+  line_comment	//   3. The unary operator symbol ~ maps to the library Function DataFunctions::'~', as shown in Table 5. This abstract Function may be given a concrete definition in a domain-specific Function library, but no default definition is provided in the Kernel Functions Library. If no domain-specific definition is available, a tool should give a warning if this operator is used.

+  line_comment	// Notes:
+  line_comment	//   1. Even though it is not explicitly represented in the text, a PortDefinition is always parsed as containing a nested ConjugatedPortDefinition with a PortDefinition Relationship pointing back to the containing PortDefinition. The abstract syntax for ConjugatedPortDefinition sets its effectiveName to the name of its originalPortDefinition with the symbol ~ prepended to it (see 8.3.12.2). (See also 8.4.8.1.)
+  line_comment	//   2. The notation ~[QualifiedName] indicates that a QualifiedName shall be parsed from the input text, but that it shall be resolved as if it was the qualified name constructed as follows:
+  line_comment	//     • Extract the last segment name of the given QualifiedName and prepend the symbol ~ to it.
+  line_comment	//     • Append the name so constructed to the end of the entire original QualifiedName.
+  line_comment	//   For example, if the ConjugatedPortTyping is ~A::B::C, then the given QualifiedName is A::B::C, and ~[QualifiedName] is resolved as A::B::C::'~C'. Alternatively, a conforming tool may first resolve the given QualifiedName as usual to a PortDefinition and then use the conjugatedPortDefinition of this PortDefinition as the resolution of ~[QualifiedName].
