      Description

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

      Lines 2498-2499
      "If the Client remade a subscription after the initial transmission of a PUBLISH packet ..."

      "remade" – does that mean resubscribed or maybe recreated? According to [MQTT-3.8.4-3] this would replace the current subscription, even if it has a new identifier. This means the old identifier wouldn’t be valid anymore. The paragraph is a bit confusing, so I’m not sure what we mean by remade and how a subscription might end up having 2 identifiers (an old and a new one).
