Как удалить префикс e: из библиотеки Spyne?

from spyne.application import Application
from spyne.decorator import rpc
from spyne.model.complex import ComplexModel
from spyne.model.primitive import String, Integer
from spyne.service import ServiceBase
from spyne.protocol.soap import Soap11
from spyne.server.django import DjangoApplication
from spyne import Unicode
from django.views.decorators.csrf import csrf_exempt
from lxml import etree

class StatusData(ComplexModel):
    date = String

class AppealsExternalStatusRequest(ComplexModel):
    messageId = String

class DataWrapper(ComplexModel):
    AppealsExternalStatusRequest = AppealsExternalStatusRequest


class AppealsService(ServiceBase):
    @rpc(DataWrapper, _returns=String, _body_style='bare', _operation_name='data')
    def receive_status(ctx, data_wrapper):
        print(data_wrapper)
        return "Received"


soap_app = Application([AppealsService],
                        tns='certain_path,
                        in_protocol=Soap11(validator='lxml'),
                        out_protocol=Soap11())

django_soap_app = DjangoApplication(soap_app)
django_soap_app = csrf_exempt(django_soap_app)

Когда я пытаюсь получить доступ к этому через http://localhost/soap_api?wsdl, я получаю в таком формате:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="path" xmlns:e="app.soap_service">
   <soapenv:Header/>
   <soapenv:Body>
      <v1:data>
         <e:AppealsExternalStatusRequest>
            <!--Optional:-->
            <e:messageId>?</e:messageId>
            <e:statusData>
               <!--Optional:-->
               <e:date>?</e:date>
               <!--Optional:-->
            </e:statusData>
         </e:AppealsExternalStatusRequest>
      </v1:data>
   </soapenv:Body>
</soapenv:Envelope>

Но я хочу удалить эти префиксы e:, как это возможно?

Я добавил namespace в этом случае, он добавляет просто другие префиксы, а когда я удаляю namespace, он добавляет e: префиксы.
