The problem with that wordview is that Xpath/Xquery are clearly mostly
going to be used at application run-time. I think the proportion of
cases where XMLSchema validation happens at application run-time is
going to be way short of 100%. I personally think's actually going to
be way short of 25%, it's useful for design support and debugging but
it's just not at the right level for business-logic validation.
The basic notion getting wired into XQuery and friends that you've
basically always run it through a schema is theoretically interesting
but WRONG.

I see no evidence in XQuery in any evidence whatsoever in simplicity.
