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) http://stackoverflow.com/questions/3555211/steps-and-involvement-of-implementing-a-parser-in-net-and-in-this-case-xpath You could (in theory) use this to write an xpath validating your grammar and call that from, say, a schematron rule.
