The work-around would be to create one unified "module" for each target namespace.  That's not such a big deal.

Schemata with large data dictionaries are cumbersome, and examples of large data dictionaries are all around us: EDI, HL-7, etc.  Most individual message types only use a small subset of the actual data dictionary.  The individual message types -- once distilled -- are more portable, easier for humans and machines to process, etc.
