SOAP header mapping is completely standard, and perhaps equally important, it can be different on the client and the server without impact to interoperability. This means you might get a WSDL that doesn't define any headers, or defines headers but doesn't map them into message parts, and you can add/change the mappings without changing the transport-level messages. I don't know if it's supported by other engines but I've seen a good number of WSDLs in the wild that use this approach. cheers, alex
