[Zope] xform in zope 2.8

Does anybody know how to monkey patch 2.8.0 so zope can process an xform? I found the xmlFix patch but a fellow zope user pointed out that 2.8.1 breaks the monkey patch because of the zope.app.publication.HTTPPublicationRequestFactory object. Does 2.8.0 have the HTTPPublicationRequestFactory object? I cannot find it but then I also cannot seem to process the xform. Thanks! Tim
