[Soap-Python] How to interact with SOAP service from client perspective ?

[Raphaël Barrois]

Hi Lukasz,

I encountered the same issue recently with suds and a .net-generated WSDL, so I wrote a patch — works great in production for a few months.
I'm planning to submit it upstream if I can find an example WSDL suds cannot parse.

Hope it helps !
