My hypothesis is that XML is better for generating function calling with schemas.
Need to write a parser that can read this:
https://github.com/SchemaStore/schemastore/tree/master/src/schemas/json
and convert to XML format that the model can digest easily.
Then evaluate the % performance between Claude, GPT 3.5, GPT 4 at satisfying the requirements in the schema as XML vs. as JSON Schema.
