For now, you might want to use getAttributes() and do a little manual 
iteration.  Maybe write a utility method.

Once upon a time a null namespace would mean to match any, but I don't 
think that's in place anymore.

I think I'd prefer to avoid opening up the namespace can of worms unless 
we had a really compelling reason.  :)

A wildcard esp would be a pain because it would have to be rejected for 
use as a normal namespace, one that's attached to nodes.  You can't 
construct an element with ANY, for example.  This is why Michael's 
approach of a separate type would be better.  But that's a lot of mess 
for something that could be done with a little iteration.  (Iteration 
isn't even slower, as it's what's done internally, because attribute 
lists are assumed short.)
