Why do you say it helps you with neithe ?

Based on the WSDL I know what the input and output for the portType
is.

SOAP will help me send the input information across the wire and
get the output information for that service.
What I do with that information is upto me...

Thats half the problem. The other half - dynamic contract negotiation-
I agree is not possible with this scenario and may be a completely
different story.
