Type of Assignment:
Registration of “mqtt” token

Registry:
Application Layer Protocol Negotiation (ALPN) Protocol ID

Description:
The mqtt protocol has the protocol version written into the first message on a connection. The mqtt server implementations typically understand the protocol version based on the fixed header on the first message (connect).

Adding this protocol id to the registry will help the community since clients wanting to request mqtt as the protocol would have an appropriate specification reference to use.
