I've just posted a source code release of some XChart stuff ...

Inside you will find a bunch of SAX and SAXON stuff which implements a
multistage XSLT transform pipeline. The HTTP form CGI variables are injected
into the SAX chain which starts the transform pipeline. At each stage a
com.megginson.sax.XMLWriter saves intermediate results to transaction
directories. The org.openhealth.saxon.OpnoteServlet java class implements
this pipeline and is an example of using SAXON with the TRAX API.

A live demo of this is available at
http://www.openhealth.org/opnote/Opnote.htm

(there are still a few little nits i have 'upgrading' to the latest version
of SAXON...)
