Or you can argue that each class represents an Element.  The enclosing Document
is merely a container for all of these elements.  In the XML Framework we have
done, this is exactly how handlers are used for Elements by logically mapping XML
Elements to Java classes.  The handler for every sub-element is dynamically
generated as needed.  You could say this is a data-driven approach and works
quite well for most applications, but for some applications I can see its
limitations.
