I think a combination of our approaches could work: the only difference
(apart of the code elegance) is that my patch grows this alist on its
way down the tree as it encounters new namespace. This meshes well with
the namespace declaration, which scopes recursively down the XML tree.

This afternoon, while I sit at the e-Lok waiting for the FSFE meeting
is a very good moment for me to look into it. I'll report tonight :-)

Thanks & later (dayjob calling)
