Figure 3-16: SleSmExceptionResponse, Presented in a Class Diagram
In all cases the complete document (unrecognized message set) is returned to the Sender as
part of the message.
InvalidMessageResponses are returned by the Receiver for messages that cannot be
processed either because they violate sequencing requirements or because they invoke
operations or notify events that are not supported by the Receiver.
The UnrecongnizedMessageSetResponse and the InvalidMessageResponse
documents each have a diagnostic parameter with values specific to the type of message.
For this reason, two tables are provided for the definition of the values of the diagnostic
parameter, one for each of the message types.
3.3.4.4.2 Parameters
The constituent data set of the SleSmExceptionResponse messages are defined in
tables 3-20 to 3-24.
