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.
