All,
I wrote a simplier implementation.   I think I the ANTLR based
version.   I have a bunch of queries of the form:

select person from customers where lname = 'Stang'

I saw your grammar and thought of using your grammar instead
of mine, mine doesn't use XPath.   However, since you are going
to create a Xindice implementation, I think I will wait and see.
If you need help help let me know.
