  All this is in the context of XML. In XML data models, XML Namespaces
declarations are some kind of children (either attributes or specific type
of nodes) of the element holding it, and those can only be referenced from
nodes which are in the subtree of said element.
  Don't expect libxml2 doc to replace the XML specifications. The
libxml2 docs s ore nly related of the specifics of that implementation.

  They should be clear to anybody who understand XML, which IMHO is a 
prerequisite to code XML related applications or libraries.
