There's no problem adding Namespace support to SAX -- after all, you
can stack SAX filters on top of each other.  John Cowan wrote a
Namespace filter for SAX about a year ago, and I have a fairly
high-performance one that I just haven't had time to package and
release yet.

The problem is the lack of a standard way to tell whether a SAX driver
already supports Namespace processing natively (and, thus, doesn't
need a filter), together with a standard way to turn that processing
on or off.

All the best,
