Hi Jack,
The problem here is that your schema defines *abstract* types, which
cannot be used directly in XML documents. You need to have concrete
types that extend the abstract types in order to actually use them in
documents. Judging from the binding error you're getting, it looks like
there aren't any concrete types for these abstract types.
Are you working with the complete schema? How are these types used in
the actual instance documents? If the abstract types are never actually
used then you can just use a code generation customization to skip
generating the classes and bindings for these types.
