I can't see much core code being shared to be honest. However, the
benefits of merging would be more apparent to clients of these modules
who want to be able to use z3c.schema2json and z3c.schema2xml together
to support both serialization formats.

I can see two use cases from the perspective of client code:

 * I want to have my objects serialized and deserialized but don't
want to know what format is used, just use an agnostic interface
(z3c.autoinclude wires the correct implementation from the list of
dependencies).
 * I want to present a list of possible serialization formats and have
the user select the appropriate one.

Thanks,
Paul
