I don't see a big downside with this approach.  We just document that 
for the special case of any URIs which by spec fiat cannot be the 
default namespace, we return their special namespace.  Right now that's 
only the XML namespace.  The spec made it a special case (don't see why 
that was necessary) so it's prob best if we follow along.

Correct.  We can enhance the docs.

We can also document that more.  I wish the namespace spec had given a 
real name to the thing you call the non-namespace.

Thanks for the suggestions,
