Constructs a complete schema, including user-defined types not referenced in the schema directly (for example interface implementations).

Fragments can only be declared on unions, interfaces, and objects. They are invalid on scalars. They can only be applied on non‐leaf fields. This rule applies to both inline and named fragments.

Variables can only be input types. Objects, unions and interfaces cannot be used as inputs.
