I don't recall XML Schema permitting multiple redefinitions of the same
element type, but I may well be missing something.  Seems like obviously
dangerous practice, in any event.

To the W3C XML Schema-aware, it may look "special" and have a local
context, but to the rest of the world, it looks as if it had been
explicitly declared not to be special.  The context understandings
surrounding this usage are not intrinsic to anything in XML
1.0+Namespaces.
