Section 1. says "An XML namespace is a collection of names, identified 
by a URI reference [RFC2396],"; this is echoed in section 2., which says 
  "The attribute's value, a URI reference, is the namespace name 
identifying the namespace."  Agreed that none of the apparatus of 2396 
is copied in, so the constraint is strictly by reference to that RFC.

Is this a problem? -Tim
