We had a similar issue in Plone recently: how can add-on products extend
existing content types and their schema. What we ended up with is the
idea that types have a basic schema, but by using a schema adapter we
can let others modify the schema. This resulted in
http://pypi.python.org/pypi/archetypes.schemaextender) which seems to
solve this nicely. I suspect a similar pattern can be used here.
