I think Paul Prescod's EasySAX Python package represents a large change in
this discussion - there was both SAX and DOM bashing in his XTech
presentaiton but the end result was an approach that combines the two.  I
think EasySAX may be the start of something new, and it might well be worth
creating a Java-ized version of it.  (If only I had the time.)

It doesn't look like Paul's slides (or EasySAX) are up at his site yet, but
I wrote a brief XML.com article on it:

The same article covers RELAX, which I think may represent an important
turning point in the schema discussion.  It uses XML Schema datatypes, but
has its own vocabulary for structures - a much simpler one, though with
some features unavailable in XML Schemas.  Well worth a look.

There were some amazing presentations there.  Yes, there was some marketing
creeping in, but there was plenty of good food for thought as well.
