SOAP Messages

The Task Execution Web Service expects messages from the client to have the following characteristics:

Message exchanges between the client and the web service are in the form of a SOAP Request-Response message exchange pattern (MEP).
The ultimateReceiver for all requests is the web service.
The web service throws a fault for any MustUnderstand SOAP header block. Also, NotUnderstood header blocks are generated for headers that cause this fault.
A binding on a web service-enabled operation is a SOAP binding in the document binding style.
