Well ... this is getting off the topic of the thread, but actually I
don't think is true. Maybe you are forgetting that you have recursion
with the cocoon: protcol. With URI matchers and selectors I think this
is all you would need. The request URI would play the role of the tape
of the Turing machine.

It depends on how much you expect from it of course. I agree it would be
foolish to imagine that a validator could prove that a site map was
totally "solid" in the sense of being logically correct. If you
appreciate that the schema doesn't prove that your web app will work
correctly, a schema could still be quite useful purely as a syntax
checker.

It might be more useful to use a schema to help MAINTAIN validity while
editing a sitemap. There are a few XML editors that will give you
context-sensitive assistance for editing a document based on a schema.
e.g. http://pollo.sourceforge.net/cocoon.html
