"Heavily discussed but I don't think it will ever appear."
That's a real shame. Personally I think that lack is the single major
missing part of JDOM. Most of the other niggles are just that. Maybe I'll
have to go hack the source ;-)

"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."
Ah, I don't think I was on the list then. I'll have to go see if I can find
