- using multiple unrelated default namespaces?

Answer 1

Yes.

In the case where you have multiple default namespaces, in the specification :

The default declared namespace extends from the start of the start tag, in which it is displayed to the end of the corresponding end tag , excluding the scope of any internal namespace declarations .

Answer 2

Yes.

(that's all I was going to say, but StackOverflow doesn't like short answers).
