As already noted, this is illegal according to the namespaces spec.

You would indicate it by not using foo:baz! The *only* way to get
an element that is in no namespace is by using an unprefixed name:
(The xmlns="" won't of course be necessary if nothing outside binds
the default namespace.)
Is it a problem that prefixed elements can't be in no namespace? Not
a serious one I think, just a small non-orthogonality. In particular,
since they can't happen, you never have to worry about fixing them up
when cutting-and-pasting them between documents. For example, if you
want to insert this document:
into this element:
then it's important that you can undeclare the default namespace:
But you never need to be able to do the same when inserting:
since it cannot have been in no namespace to start with.
