[XML-SIG] SAX Namespaces

[Greg Stein]

Each of these presumes that the namespace processing can be turned off. Is
that an important/required feature? IMO, the NS processing can/should always
occur; they are an integral part of XML processing today. The presence of
namespaces doesn't impact older documents either.

[ well, there is the case of somebody using ':' in an XML element name but
  NOT using namespaces. but holy smokes... I don't think we should introduce
  variations in our APIs based on this edge case. ]

[ nit: how is #5 different from #4? ]

I would take option (1) or (3). qname would be the prefix used. If NS
processing *can* be disabled, then uri==None and name==qname.

Cheers,
