hi Tom you kind of need to set the ground rules for this. It's not really practical to use schematron to do detailed terminology validation. Must serious attempts end up creating some kind of web service terminology server that can be invoked from the schematron rules.
Once you've done that, you've got a relief valve for things that are too difficult to express in xpath - because xpath is really good for some things, and really not so good for others. But also, once you've done that, you're not really using schematron anymore...
