How are duplicate SUBSCRIBEs handled?
-------------------------------------

                 Key: MQTT-59
                 URL: http://tools.oasis-open.org/issues/browse/MQTT-59
             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
          Issue Type: Improvement
          Components: core
            Reporter: Allan Stockdill-Mander 


This issue is related to MQTT-58

If a client has a subscription to a topic and then issues a SUBSCRIBE to the same topic does it have two subscriptions (and depending on MQTT-58 receive two copies of each message) or just one? If the latter case do the values of the new SUBSCRIBE (such as QoS) replace those of the original subscription?
