[XML-SIG] Sax and Dom readers

| When we speak of sax, we mean SAX 2.x, since SAX 1.x is obsolete.
| the xml.dom.ext.reader still has a Sax.py and a Sax2.py. Lots of
| newcomers use xml.dom.ext.reader.Sax, maybe because of slightly out
| of date docs.

Good point. There are various historical reasons why things are as
they are, but we should make a plan to get rid of the SAX 1.0 legacy.

I need to look at the sources again to see exactly how we ought to do
this, but I can't do that before Sunday.
