The answer to all your questions is basically no. If you want to marry
the two APIs there are basically two ways: propose specific and minor
changes to SGML::Parser::OpenSP (I could for example adapt the way the
attribute values are reported), or write a handler that acts as a SAX
parser would. I did some work on both approaches, but mainly in fixing
the Perl SAX specification and implementations thereof. I think a small
wrapper should be easy to write; a complete one that takes care of the
different approaches to positioning information reporting, error re-
porting, SGML-specific features, etc. would be much more difficult. I'd
recommend to start with a wrapper and see what changes to spo might be
useful.
