Summary: pyexpat LexicalHandler swaps system_id and public_id

Initial Comment:
XML:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE A SYSTEM "a.dtd">
<A>test</A>

DTD: you can imagine

...
ch = MyHandler()
parser = make_parser()
parser.setProperty(handler.property_lexical_handler, ch)
...
class MyHandler(XMLGenerator):
...
    def startDTD(self, name, public_id, system_id):
        self._out.write(public_id)
...

-> "a.dtd" (but a.dtd should be the system_id) and the 
system_id in method startDTD is None

a glimpse into pyexpat.c from python 2.2.3 
...
VOID_HANDLER(StartDoctypeDecl,
...
STRING_CONV_FUNC,doctypeName,
              STRING_CONV_FUNC,sysid, 
STRING_CONV_FUNC,pubid,
              has_internal_subset))
...

maybe sysid and pubid is swapped.

I'm not a python specialist and maybe this bug is fixed or 
is not a bug. Please let me know...
