Subject: xmlns scheme - default namespace definition



While going through comments on the
old XPointer CR, I came across an issue
with xmlns() -
How to set the default namespace?

Assume we want to set the default namespace for
a pointer part. How do we do so? The current
grammar does not allow
  xmlns(=http://example.org/ns)

Do we simply change production 1 from
 xmlnsschemedata ::= NCName S? '=' S? NsURIRef
to
 xmlnsschemedata ::= (NCName S?)? '=' S? NsURIRef

Something else?
