Adding a message
Messages represent an abstract definition of the data being transmitted. A message consists of logical parts, each of which is associated with a definition within some type system. WSDL messages are top level objects that can be referenced by an operation's input, output and fault elements (within a port type).
Information noteNote: Changes of service elements are not automatically propagated to bindings. You need to
regenerate the binding content and select the Overwrite existing binding
information check box in the binding wizard to reflect changes in the WSDL. For
more information, see Setting a binding.
