I haven't read a recent schema draft, but if it says what you say it says,
then in my opinion that would be an egregious design error.  It is of course 
not a violation of the namespace spec, but I'm beginning to think that we 
should have written into the spec an express prohibition against land-grab 
attempts on the address function of the namespace name.  The notion that a
single URL can address the One True Schema Which Will Meet All Needs is 
demonstrably, empirically, absolutely wrong.  -T.
