Some Comments

1.  If a requested QoS is 3 in subscribe, it is not clear whether
this 

is a malformed packet which should cause the session to be terminated,

or whether a suback should be returned with invalid request or lower 

granted QoS.  (I think the first case is intended.)

2. When receiving a publish with the retained flag set and a payload of

0 length, it is clear that any existing retained message should be 

removed.  But what if there is no existing retained message?  In
that 

case it is not clear if we set a retained message of 0 length, or not.

(I expect not).

3. # wildcards used to be allowed at the beginning of topic filters as

well as at the end.  Is this a deliberate restriction?

Ian
