	I have to say, we've got a specific set of schemas, and we're only
going to write this code once.  Many of the XML mappers have kind of left
a bad taste in my mouth.  If we use DOM -- the DOM that's included in JDK
1.4 -- then we have guaranteed compatibility, no library bloat, and great

	That said, it's not quite true.  We will need to adjust the 
Geronimo DDs over time.  But my experience has been that all the tools 
need to be customized to operate the way we want, whether it's to change 
generated class names or handle the mix of attributes and content in some 
of the J2EE tags.  I personally find it as easy to write the code to pull 
stuff out of a DOM tree as to write the Betwixt or Digester rules, and 
far easier to debug as well.

	The one remaining obstacle is XPath, and we just have to decide on 
the library bloat issue.  It wouldn't be terribly hard to write the 
minimal XPath processor we need (operating on the POJOs), but JXPath does 
it already...  Plus, it debugs well.
