It's an interesting point, though the W3C has done exactly this in other
XML specs - XML Linking, XML Pointers, XML Path, XML-Signature, just to
name the ones I can think of offhand.

Given that we had to change the name of XSchema to DDML as part of the
submissions process (to avoid confusion, if I remember right), I suspect
they feel somewhat proprietary about the XML name.

Schemas is the only field I've seen where their 'XML'-named spec is facing
real (and sustained) competition, so it's kind of a tricky precedent.  I
can see where they might not have expected (or desired) competition, so
they did it like the others.  As circumstances have developed, there are a
lot more options than the W3C's creation.  But since people tend to start
looking for XML specs at the W3C, they may never even hear of the
competition...
