I'm sorry, but I would rather say "non-standard yet technology". Lots of
people have implemented push-processing that can handle context-sensitivity.
Basically, just add a stack in your ContentHandler and you're done. Just add
some association between a stack configuration (equivalent to a kind of
canonical XPath of the current element) and a piece of code to execute, et
voilà ! You're processing data in a context sensitive way. That may be
slightly more complicated than a switch statement or an hashtable keyed on
the  name of the element, but that's not rocket science either.
