The lower right panel displays the error and warning messages from the selected WSDL document WS-I compliance report, with type, message, and reason for non-compliance via the error code.

With this backend type, each method of the UDPDMI contains code to obtain the WSIF service, create the input WSIF message, pass it to the WSIF operation, and process any return message.

I also incorporated code to query the type of incoming message (Listing 13) and explicitly set the attachment type (Listing 14) into the implementation of a basic handler (Listing 7).
