The XML-RPC service wrapper makes use of the 'xmlrpclib' module. As such, any types supported by the 'xmlrpclib' module can be used. Faults can also be raised using the 'xmlrpclib.Fault' class. Where the first parameter of a function is the 'req' parameter, it will be passed the mod_python request object."
