WSDL learning notes: multi part in message

In WSDL 1.1 definition, we can declare one or more parts in message. But we still can choise only one part to be the request message of a service. It can defined at <soap:body /> tag in binding. And use parts attribute to allocate which part that the service's message want to use.

If you use rpc as your binding style, you can use type as message's part. But if you use element as message's part, you have to use document as binding style.
