Big question: can I plug someone else's SAX parser into your scanner, and
then have your validation component work on my SAX events?  While it's
unlikely that I'd want to plug a different SAX parser in, it's quite
possible that I'd want to work with the SAX events (transforming with XT,
for instance) before performing validation.
