I want to propose a restriction and an extension:

1) This method cannot be called after any other parser method
has been invoked.

2) This method is allowed to throw a SAXNewParserException, which
encapsulates a replacement parser.  The application should use
the parser inside the exception in place of the original parser.
This allows parsers to push filters on top of themselves, which
complements the ability of applications to push them.
