It would help the rest of us wrap our heads around the problem if you
could provide a sample fragment of the "semantics-defining file" so we can
see what you are dealing with.

You may be able to create the tests you want in Schematron, but it's a bit
hard to tell without having an example to look at.  (If you can generate
Schematron from your definitions, you could directly create XSLT for the
axis tests about as easily, but the advantage could be that there are
tools such as XML IDEs that already understand the Schematron report
