  No, basically libxml2 separates the namespaces when parsing, and move
them out of the attribute list. Check an xmlNode structure, if it uses
a namespaces then it has an ns pointer pointing to the namespace
declaration. And when a namespace is declared the associated xmlNode
of type XML_ELEMENT_NODE will have it on its nsDef list of namespaces.

  Note that: 1/ the root element may not carry all namespaces for the
                document
             2/ there is no routine to search for all namespace
                declarations within a document (doesn't make much sense)
                but there is a routine listing all the namespaces
                in scope on a given node (xmlGetNsList)
