I have looked at XMLRPC some time ago, but I forgot most details:

  If XMLRPC supports keyword (i.e. named) parameters,
  then Zope will handle the parameter passing transparently
  for you. You must use the same keyword parameters your
  have defined in the ZSQL method.

  If XMLRPC supports only positional (i.e. unamend) parameters
  then you must use as a wrapper a method type
  that supports positional parameters (Python method/External method).

When you call DTML objects yourself, you must pass the context
explicitely:

	   return self.index_html(self,REQUEST)
