------------------------------

             Summary: Add User Defined Property to ACKs
                 Key: MQTT-321
                 URL: https://issues.oasis-open.org/browse/MQTT-321
             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
          Issue Type: Bug
          Components: core
    Affects Versions: 5
         Environment: This was discussed in MQTT-276 with notes from the F2F meetings and has been tracked in MQTT-256. 

I'm opening a separate, specific issue per Ken's comments - https://issues.oasis-open.org/browse/MQTT-256?focusedCommentId=62192&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-62192: 

"All of these would be defined in separate JIRAs, but what we should do in this JIRA is to define the mechanism used to pass these values." 
            Reporter: Ed Briggs
            Assignee: Ed Briggs


The working drafts do not yet include the ability to return a user defined property (key value pair) on acknowledgements (CONNACK, PUBACK, PUBREC, SUBACK, UNSUBACK, and DISCONNECT).  This was part of the original requests.  The purpose of these properties is to allow the return of implementation specific information and hints (e.g. 'You exceeded your message quota, try again in 15 minutes'.)

This field is not parsed by the MQTT implementation.
