Me included.  :-)  Brad did a great job in jdom-x sketching out the 
design and potential.

Heh, I plan to placate people by quickly getting to 1.0 so this is the 
last major overhaul they'll need to make!  I just couldn't justify 
getChildren() returning Elements only when Child clearly includes all 
content.

It's the knowledge we needed a few of these major changes that kept us 
in beta without an API freeze.  I'm glad most of the tough stuff is 
behind us.

Main things remaining:

* Try to remove the number of protected fields and methods in
   SAXHandler, SAXOutputter, and XMLOutputter.  Use the strategy pattern
   instead perhaps.  (Advice welcome!)

* Experiment with javax.jdom.Element interfaces.

* Figure out what we do about the JCP.

Brad also had some XMLFilter things he was working on.
