So, if I walk up the DOM tree from my current node to the root and take the union of the namespace nodes at each DOM Node will I have the set of all namespace node?

Yes, that's correct.  You get all of the in-scope namespace nodes, but
they are not necessarily parented as you would expect.

It's really a DOM-style implementation, and the namespace axis just goes
up the tree and gathers up the nodes.  So, this breaks when you really on
generate-id() as a hack to implement node identity, and also in the case,
where you use the parent axis.  In the first case, there's no work-around,
while in the second case, there is.
