I agree that this could happen if branches would be build without
documents or branches from other documents would be added. But I think
there are different scopes of use. And if you want to use full
namespaces support for XPathes you need to build your document in order.
In addition you always have the chance to add namespaces by yourself to
the context if you do some special operations.
If we want to support all cases of structure changes and removes it will
be really costly. I think this would be overdone.

Not really. For an xpath you could use each of them. The point for me is
to have the chance to have all namespaces with prefixes that could be
needed by an xpath for the given document (or branch). And in most cases
you have only the ones from your document and this will be better as for
example use all namespaces from the namespace cache wich means the
namespaces from all documents that where created since the vm start (and
this will result in many problems with doubled prefixes).
