      4.7.2.1 Subscription handling reads in part:

      *****
      Non normative comment.

      ... (last bullet item)

      For a Client to receive messages from topics that begin with $SYS/ and from topics that don't begin with a $, it must subscribe to both "#" and "$SYS/#"
      *****

      Is that "must" simply an observation based on how the protocol works or is that a substantive requirement?

      I ask because your other 141 uses of MUST are all uppercase and in normative text.
