I just wanted to mention something you should keep in mind when you're 
doing this:  the stylesheets that take many minutes to run processing a 
single input are interesting and important, but at least as important are 
stylesheets that will be running on a server, processing hundreds of 
requests per second.

If you can find a copy of the XSLTMark benchmark tests anywhere, you might 
want to try them out - they aren't necessarily the best, and don't 
necessarily reflect typical usage on a server, but there haven't been many 
other XSLT benchmark tests published.

Something else to consider - most of the performance work that's been 
carried out in the Apache Xalan-Java project, other than early on in the 
project's history, has been focused on the XSLTC processor rather than on 
the Xalan-J interpreter.

Thanks,

Henry
