Rather than subclassing SAXBuilder and Element to support
listeners (with the modifications you suggest), wouldn't it be
more extensible to "fully articulate" the class hierarchy in the
manner of Swing? By this I mean: define an Element interface, an
AbstractElement for subclassing, and a DefaultElement for the
masses. And so on down the line. Note that DefaultElement is
essentially what Element is now.
