later interpretation by a SOAP-aware view.  Without this patch SOAP requests
fall into the XML-RPC logic and cause errors.

This patch does not add significant overhead nor introduce new functionality
other than making it possible to cleanly add-in a 3rd party SOAP parser for
those who want it.  This technique is being used with views using a small
wrapper of soaplib and a @soapmethod decorator, outside the Zope SVN.
