Pain of ambiguity, I'd call it.  If you're crazy enough to use xml:id
AND another attribute of type ID, there will be pain down the line, sure

As Namespaces in XML didn't modify XML 1.0's rules for validity,
introducing a different class of constraints instead, I'd say this
probably should go the same route.
