Hi!

Can someone explain why we have, in the following code, the handling 
for NS==None in tag names, but not in attribute names? Smells like a bug.

    def startElementNS(self, name, qname, attrs):
        if name[0] is None:
            name = name[1]
        elif self._current_context[name[0]] is None:
            # default namespace
            name = name[1]
        else:
            name = self._current_context[name[0]] + ":" + name[1]
        self._out.write('<' + name)

        for k,v in self._undeclared_ns_maps:
            if k is None:
                self._out.write(' xmlns="%s"' % v)
            else:
                self._out.write(' xmlns:%s="%s"' % (k,v))
        self._undeclared_ns_maps = []

        for (name, value) in attrs.items():
            name = self._current_context[name[0]] + ":" + name[1]
            self._out.write(' %s=%s' % (name, quoteattr(value)))
        self._out.write('> ')

What I get is this:
<?xml version="1.0" encoding="iso-8859-1"?> 
<bibliography> 
!!!! The following are the args to the __init__ of AttributeNSImpl!
  *** Attrs = {(None, u'id'): u'prescod:1999'}
*** Qnames = {(None, u'id'): u'id'}
