In XOM, the name always comes before the URL. Flip the order of your 
arguments, that is:

aElement.getAttributeValue("attribute", "http://test.org/Test";)

Hmmm, I wonder if there's an inexpensive way I could test this on 
getAttributevalue (and many similar calls) to warn the user what 
they're doing wrong at least some of the time. If this were a 
constructor, then there would be an exception here, but even there 
perhaps the exception could be clearer?
