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?
