I was looking at STX too but couldn't find a way to use it from Java. 
Anyone know how you use it without making an stx file?

I understand the issue with xpaths and needing DOM. I know xalan has its 
Document Table Model (DTM) that improves on performance. Anyone know if 
we can tap into that without writting a XSL file?
