Just a lurker on the list, but...

My vote is for no factory for element creation, and little or no up-tree
checking.  What drew me to JDOM in the first place were its simplicity (I
can teach a Java newbie how it works in no time; a factory is a higher-level
concept and removes the "new" syntax that people are used to when creating
new objects), and its speed (heck, even the O'Reilly book says it's nearly
as fast as SAX).  I think we're making this overcomplicated for the
relatively small number of problems that would arise.

Why not just throw an exception when XMLOutputter hits an element it already
touched?  That would at least alert the programmer that they're
creating/adding elements in a bad way.  Or perhaps add a method to Document
that would remove any infinite element recursion?
