I've written what I call a half-parser, available (in Java) as part of my
Gorille project. It reports every character in the document and stays away
(for now) from entity expansion, attribute defaulting, and other infoset
excitement. It also has a context object which makes it easier to handle
issues like entity values and namespaces.
Gorille is at:

Details on Ripper's API, which should give you a good idea what's included,
are at:

A paper explaining this more thoroughly is at:

A presentation on it in English is at:

A presentation on it in Playmobil (requires SMIL, in RealPlayer One) is at:

I'm planning a lot more work surrounding this parser, but have a painfully
serious shortage of time at the moment. There should be a lot more in 2004.
