Fixed.

Fixed.

This is effectively fixed now, assuming that the XMLNS spec prevents 
attributes in the XMLNS namespace from being placed in ways that would be 
contradictory to their semantics (e.g. assuming it's not legal to have an 
xmlns="http://example.com/" attribute in the XMLNS namespace on an element 
without a prefix and that is in another namespace).

Isn't this a given? What would require them?

Fixed.
