Add help info near "isComposite" and "isReference" checkboxes in Details view

[AxelRICHARD]

The role "isComposite" and "isReference" checkboxes in Details view can be confusing for end-users.

• "isComposite" checkbox can be edited.
• "isReference" checkbox cannot be edited. It is the opposite of "isComposite" value.

An enhancement could be to add an "help" (the little question mark icon) near those two properties, with the following messages:

• "isComposite" checkbox: "opposite value of isReference"
• "isReference" checkbox: "opposite value of isComposite (cannot be edited, edit isComposite instead)"

There is already som examples of help icons in the Details view:
