I have a very strong feeling that we should NOT try to change/extend SAX.

The most sensible thing to do is to implement SAX2 over BER and PER (using
schema information) in such a way that TEXT, and only TEXT, is presented to
the application.  

The application should receive the same series of callbacks, with the same
parameters, regardless of whether PER, BER, or XML is being parsed.  In
other words, the application should not be aware that PER or BER, rather
than XML, is being parsed (*).  When writing, the application should not be
aware that PER or BER, rather than XML, is being produced (*).  

This would enable us to use ASN.1 technologies and XML technologies together
easily.  A "binary-enabled SAX", instead, wouldn't take us anywhere.

(*) except, perhaps, when initializing the parsing process or the writing
process
