Construct Message Shape
Use the Construct Message shape to construct a new instance of a multipart message type. It must contain either a Message Assignment shape or a Transform shape, and can contain any number of either, but no other shapes. You specify the message variable that you want to construct, and make assignments to the message or its parts. All assignments to any given message must take place within the same Construct Message shape. If you want to modify a property on a message that has already been constructed—such as a message that has been received—you must construct a new message instance by assigning the first to the second and then modifying the property on the new message instance; both the construction and modification occur within the same Construct Message shape.
