Heavily discussed but I don't think it will ever appear.

Are you talking about SAXBuilder?  There have been about 3 different
approaches suggested to allow subclassing the jdom classes, all of which
have some merit.  Ken Rune Helland (3/13/01) submitted a version that allows
you to specify subclasses to use via a factory.  Jason is hoping for
comments but there haven't been any yet.  How about you?  Or maybe I've
missed your point.
