Well yes, obviously, but that's not the point.
The point is that namespaces imply a generic transformation which
removes everything but the elements and attributes in a particular
namespace. The resulting document can then be processed in a generic
way (I don't need to point out to you that this is an AF-style view).
That is, namespaces are _simple_, and the problems consist in how you
specify this generic transformation -- that is, what is and isn't in
the namespace -- and the current spec complicates this by introducing
the default namespace, then ducks the problems this causes by the
evasion in section 5.2.
Also, there's no role here for the `global attribute' nonsense.
All the best,
Norman
