Overall, very nice!

My only concern is that LexicalHandler should be required by all parsers.
Otherwise you will get "fully compliant" SAX2 parsers which cannot be used to
resolve QNames found in attribute values against in-scope namespace
declarations. There are many examples where that's critical:

- evaluate XPath expression (XLST, XPointer, etc.)
- resolve XLink locator role (see
- follow XML Schema references (see

and probably more to come... 

IMHO, LexicalHandler must be supported by all SAX2 parsers.
