      The Server SHOULD retain QoS 0 messages, but MAY discard them at any time. In the latter case there will be no retained message.

      Note to editors:
      For completeness, consider providing a link in Section 2.2.2.3 "Retained" to Section 4.1 "Store" to help reader with clarity around store.

      The current specification states that :

      Retained messages should be kept over restarts of the server.

      Is this correct even for Qos=0 retained publications?
