[XML-SIG] Re: Python Web Services and .NET - will it ever work

[Joshua Boverhof]

The instance produced looks correct..  It's not always python that is 
the problem,
but w/o seeing the WSDL it's impossible to say.  I would guess that you are
using rpc/encoded bindings, and I'd also guess that the operation name
is "GetCity" and that .NET is incorrectly looking for "GetCityRequest" or
whatever the input message name is...
