Added DFN to the test cases.

Have you tested this? The test cases in the article are very  
different, and rely on the other element having another element's  
title attribute read instead of the DFN. I do not have access to JAWS  
now, but I would guess the example would still read the dfn[title].

Either way, I would hold off on re-implementation for now until the  
test cases are complete and tested. The article only mentions JAWS'  
behavior and, although it's the most popular stateside screen reader,  
it's hardly the definitive answer for what counts as accessible.
