[XML-SIG] Writing SAX-drivers

Parsers in SAX are called "readers", and they implement the XMLReader
interface, see

http://www.python.org/doc/current/lib/module-xml.sax.xmlreader.html

Optionally, they also implement the IncrementalReader interface,
documented at the same location.

I'm not sure what you mean when you say "docs only mention using SAX
interface compatible parsers". The docs obviously cannot state how you
implement your interface; they only state what the interface is that
you implement.

Python SAX closely follows Java SAX, although the Incremental
interface is a Python invention.
