This looks pretty good. If I understand this correctly, XML parsing in
libxml2 goes through the SAX2 interface and the the SAX2.c functions are
the callbacks that pass the SAX events to the higher level stuff. 

So this means I can move from expat to libxml2 (the SAX interface is
quite similiar) and put the higher level libxml2 functionality into
seperate filters, that can be glued together controlled by processing
instructions, possibly a special namespace and apache config.

The goal is to build something that can (for example) run a streaming
XPath expression and treat all matches as tiny seperate documents that
are processed by an xslt stylesheet.

Thx,
