Let me be clear: I do not believe SAX should directly support *any* 
binary data format. SAX is an API for XML, and should remain just 
that, nothing more. If other binary formats wish to interoperate with 
SAX, it is their responsibility to define a reasonable mapping into 
XML structures, not to change the XML APIs to support their non-XML 
information set.

I think it is reasonable for someone to reuse the ideas of SAX to 
create their own new API for processing their format. I do not think 
it is reasonable to change SAX itself to enable this.
