If you wanted to stick to pure xml solutions without using extensions to
another language you could look at Dimitre Novatchev's LR parser
generator written in Xpath. I thought he had a blog entry describing it,
but I didn't see that just now but here's an answer on stack overflow
giving some description and pointers to the code (which is open source
on sourceforge)

You could (in theory) use this to write an xpath validating your grammar
and call that from, say, a schematron rule.
