I like.  But I think we'll want more than just a parser factory:

properties = {"http://factory.pyxml.org/properties/encoding": "BIG5",
              "http://uche.ogbuji.net/my-extended-properties/spam": "eggs"}
features = ["http://factory.pyxml.org/properties/xpointer"]
xml.factory.getXsltProcessor(properties, features)
