Nope, it's not.  No XML document could produce that particular
sequence of events.

Not entirely.  The XML is perfectly well-formed, but it's not
namespace-compliant.

| <ns1:doc xmlns:ns1="http://www.python.org/xml-ns/saxtest/"></ns1:doc>

What original document? :-)

I see that as being the best fix, and have now committed it.

We could do that, but the namespace name and the qname are supposed to
be equivalent in any case, so I don't see any reason to change it.
One problem with making that change is that it no longer becomes
possible to roundtrip XML -> pyexpat -> SAX -> xmlgen -> XML because
pyexpat does not provide qnames.
