Yes. FYI: I actually compile the schema for schema documents, which creates
a DFA for every complex type; I output an XML serialization of the compiled
schema (which can be used for fast loading of schemas); and then I have an
XSLT stylesheet that generates Java code representing the DFA which gets
copied into the schema processor.

Of course this only works once you've got a working schema processor...
