Response messages are application-defined. So, determining what is in the response message is the responsibility of the application sending the response message as well as the application receiving the response.
Two message properties that can be included in the response message are the identifier and destination of the original message. For example, the destination queue of the original message can be returned in the response queue property of the response message, and the identifier of the original message can be returned in the correlation identifier of the response message.
Other message properties, such as the body of the message, can be included as well. When designing your response message, simply make sure that all applications know how to interpret the information provided by the response message.
