No, but what is at the end of a URL when you access it is undefined - hell
it might not even be static. The namespace spec should not constrain
what's meant to be at the end of a URL, not even for the defined usage of
"identifying a namespace".

Please go back and read the ancient archives on this. Way back when the
namespace spec came out - which had to come out fast because people needed
the functionality, we started talking about alternative urn schemas. I
don't know what happened to that discussion as I lost track of XML-Dev in
moving jobs.

My point though is just this: Nothing should define what goes at the end
of a URI. If you want to put a schema there, fine. But please don't
anybody start writing parsers that try and see if there's a schema at the
end of the URI - that way lies misery for the whole internet.
