Whoops... maybe I should have done a search for "Fuchs" in the XML
Schema spec before trying to teach my grandmother to [expletive deleted] eggs.

All I can say is that I've just finished writing two transforms: one to
fix-up a schema by disambiguating all element names, and a second which
generates an equivalent transform to fix-up incoming messages. Both were
simpler than I expected - you can go a long way by using your XSD type
as an XSLT mode...
