	Hmm, if we do that, we could create a sigleton factory class to return 
you the proper implementation of the interface based on some settings it's 
got stored. At the very least, the programmer would be forced to manually 
create objects of the correct implementation. Of course, either way would 
probably break every existing JDOM program out there, as the "Element foo 
= new Element("foo");" idiom would break. Even though we could, with the 
claim "the API is pre-1.0", I'm not sure many people would be very happy 
if we did that. Design wise, it sounds fine though.
