[Soap-Python] suds: attribute of complex argument does not get namespace prefix

I'm trying to write a saop client to connect to the mks integrity soap
interface using python 2.7.3 and suds-jurko 0.6 (or suds-03.9).

However I'm stuck now with my first example because the attributes
transactionId and ItemId that belong to the complex argument I pass on with
the method lack the required namespace prefixes (ns1:...) in my example. So,
my question is, is there a means to add these?

Here's the code I have:

#!/usr/bin/env python
#
#
import logging
import suds
from suds.client import Client

# Send log messages to console
logging.basicConfig(level=logging.INFO)
# Set Suds logging level to debug, outputs the SOAP messages.
logging.getLogger('suds.client').setLevel(logging.DEBUG)

# Web service
url = "http://besrv-mks01.ta.global:7001/webservices/2009/Integrity/?wsdl"
headers = dict( SOAPAction = 'action' )
client = Client(url, headers = headers)

print client

getItemType = client.factory.create('ns5:GetItemType')
getItemType.Username = "some_user"
getItemType.Password = "secret"
getItemType.InputField = [ "Story Elaboration Notes" ]
getItemType._ItemId = "1554094"
getItemType._transactionId = "?"

print getItemType

try:
   result = client.service.getItem(getItemType)
except suds.WebFault, e:
  print e

This produces the following output:

--snip
(GetItemType){
   Username = "some_user"
   Password = "secret"
   ImpersonatedUser = None
   DateFormat = None
   DateTimeFormat = None
   _transactionId = "?"
   InputField[] =
      "Story Elaboration Notes",
   _ItemId = "1554094"
 }

When I manually add the namespace prefix to the attributes and submit the
request via curl, I get the expected response.
