wsdl

I need to create a service that will be "called back" by a third party. As a result, I need to conform to their WSDL.

Their WSDL has all of the operations defined with soapAction="", so my service needs to do the same. Unfortunately, I'm getting the error:

The operations A and B have the same action (). Every operation must have a unique action value.

In ASMX web services, there was a mode where the soapAction would not be used, but the name of the request element would be used instead. Is there some way using WCF not only to dispatch on the request element, but also to emit a WSDL with no soapAction?
