In this particular case, however, I know how to format and register the

obtaining the set of namespaces declared by the instance document in the

  Unfortunately the Microsoft API doesn't make much sense I'm afraid
(or I misunderstand it), because a namespace URI may be bound to
multiple prefixes on a document, and a given prefix may be bound to
different namespace on a given document. So asking at the document
level doesn't make sense to me.
  What you can do is ask for the list of namespaces in scope for
a given element, libxml2 has an aPI for this:

  Note that the namespace prefix used in an XPath query is not significant,
the XPath matching will be done only on th namespace name, never the prefix.
