      This issue was originally reported in MQTT-417, but doesn't seem to be addressed in WD14.

      Lines 1860-1862

      "If a Topic Alias mapping has been set at the receiver, a sender can send a PUBLISH packet that contains that Topic Alias and a zero length Topic Name. The receiver then treats the incoming PUBLISH as if it had contained the Topic Name of the Topic Alias."

      How does the sender knows whether a topic alias mapping has been set at the receiver if the message is QoS 0?
