What you've described is the great semantic problem in automating XML
mapping. There's no easy solution, because there's nothing in the schema
that tells you that, say, tag A:x maps to tag B:y rather than tag B:z . A
mapping could guess based on the typing of objects which goes where, but
there's always going to be some ambiguity with all but the simplest of
schemata.

There are semi-solutions, which mostly involve constructing a taxonomy
with RDF and using that as an intermediary. It's not something I have any
special knowledge of but you might want to try a schema mailing list
rather than an XSLT one.

There was, however, an overview talk on this solution at the XML UK
conference a few months back: the slides are available at
http://www.xmluk.org/public/ral_2004.htm#bm . You can have a look at that
and see whether it's too much programming/building overhead for you.

Cheers,
