Как заставить ZSI принять приложение/мыло + xml?

Я использую ZSI, чтобы написать клиент для вызова SOAP-сервисов моего SOAP-сервера. Моя проблема в том, что mimetype ответа, возвращаемого с моего сервера SOAP, 'application/soap+xml', который не может передать утверждение ZSI mimetype == 'text/xml'. Как заставить ZSI принять 'application/soap+xml'?

Я изменил свой клиент, теперь я получаю эту ошибку:

Это сервер:

import os
import sys
from SendSmsWebServiceImplService_client import *
from ZSI.twisted.wsgi import (SOAPApplication,
                              soapmethod,
                              SOAPHandlerChainFactory)

class GetSmsDeliveryStatusService(SOAPApplication):
    factory = SOAPHandlerChainFactory
    wsdl_content = dict(name='getSmsDeliveryStatus',
                        targetNamespace='http://webservice.smsgateway.services.sdp.peykasa.com/',
                        imports=(),
                        portType='',
                        )

    def __call__(self, env, start_response):
        self.env = env
        return SOAPApplication.__call__(self, env, start_response)

    @soapmethod(getSmsDeliveryStatus.typecode,
                getSmsDeliveryStatusResponse.typecode,
                operation='getSmsDeliveryStatus',
                soapaction='getSmsDeliveryStatus')
    def soap_getSmsDeliveryStatus(self, request, response, **kw):
        # Just return what was sent
        response.Value = request.Value
        return request, response

def main():
    from wsgiref.simple_server import make_server
    from ZSI.twisted.wsgi import WSGIApplication

    application = WSGIApplication()
    httpd = make_server('', 7000, application)
    application['getSmsDeliveryStatus'] = GetSmsDeliveryStatusService()
    print "listening..."
    httpd.serve_forever()

if __name__ == '__main__':
    main()

И клиент:

from SendSmsWebServiceImplService_client import *
import sys, time

loc  = SendSmsWebServiceImplServiceLocator()
port = loc.getSendSmsWebServiceImplPort(url='http://localhost:7000/getSmsDeliveryStatus')

print "getSmsDeliveryStatus: ",
msg = getSmsDeliveryStatus()
msg.Value = "1235689922"
rsp = port.getSmsDeliveryStatus(msg)
print rsp.Value

SendSmsWebServiceImplService_client был сгенерирован командой wsdl2py.
