You mean for the document that Roger posted?

That's an odd definition of "namespace node," to my mind.  You're 
asserting that each element node has three namespace "nodes" associated 
with it?  I would have thought that the only "nodes" were the 
declarations.  So I could see arguments for two, three, or nine such 
nodes (variation depending upon how one handled the implicit xml 
namespace declaration).

If namespaces-in-scope manifest as "nodes," do other scoped 
abstractions (like xml:lang) do the same?
