and as I pointed out in my answer to 
  http://bugzilla.gnome.org/show_bug.cgi?id=168764
you must be able to embbed XML instances in XMPP messages, those 
instances may use namespaces in attribute content or text nodes, and
the suggested API would just break XMPP completely.

  DOM and libxml2 are completely different because in libxml2 the namespace
informations are shared, if you modify the namespace node you instead of just
changing the anmespace pointer then you:

    1/ don't have to chase all the other nodes to make the same change
    2/ don't need to creat new namespaces node and try to track and remove
       the old namespace informations
