very simple:
- ns is a pointer to the namepsace associated to the node
- nsDef on elements is the lists of namespace definitions
made on this element
For example:
<?xml version="1.0"?>
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns="http://my.netscape.com/rdf/simple/0.9/">
<channel>
....
The top level element RDF will have 2 entries in the nsDef list
and its ns field will point to the rdf one. The channel element
will ahve an empty nsDef and it's ns will point to the other namespace.

Well actually the bug is somewhere else :-) . The loop should recurse
on the parent, and this is missing. 1 line patch enclosed ...
