[jdom-interest] Namespaces and XMLOutputter

[Jason Hunter]

I sent in the code I was using, the file I was reading, and the output I
was seeing.  Did you try my specific code/doc example?  Did it work? 
You didn't send in yours, so I can't reproduce your problem.

To proceed from here, we need to know if what works for me works for
you.  If my test fails on your machine, it's a config thing.  If it
works on your machine, then it's a code thing and I need you to send in
the same code/doc info I sent in so I can see the failure on my machine.
