    # qname implementation is horribly broken in Python 2.1 (it

    # with a known list first, and then possibly override them with
    # the qnames the SAX parser gives us (if indeed it gives us any
    # at all).  Thanks to MatejC for helping me test this and
    # tirelessly telling me that it didn't work yet.
