I am working on something similar, but much simpler right now.
My XPaths are just straight paths, or in other words, element types.
My initial plan was to build a DTD (or other schema) validator
(on top of SAX) which has callback hooks for custom validation
or processing. The callbacks are registered by the application
based on a path - but rather a path based on the schema object
model and not the document object model. Every node in the SOM
corresponds to a separate set of callbacks.
So far I was not thinking of anything more complex, as I think
this would be quite an effort.
