It looks like the main motivator that I find is XMPP processing. Since this is
based on an XML stream. It's like an endless document, one root element (
<stream:stream> ), and lots of elements underneath that root element that carry
the communications.

So no DTD/Schema validation is required. Because of the limitless nature, we
also need a way to emit DOM DocumentFragment(s) for each element, but not create
one huge document.

Currently the XMPP server I would like to enhance is Vysper based on the NIO
framework Mina. They do some basic home-brewed XML parsing, but moving to a
standard one might be beneficial, but speed would be of importance too.

What do you think? I was just going to create an enhanced version of a SAX
parser for Mina.
