      1. Register the sub-protocol name "mqtt" with IANA for use with the MQTT3.1.1 specification.

      2. Change the body of chapter 6 line 1757 onwards to be normative.

      If MQTT is transported over a WebSocket [RFC6455] connection, the following conditions apply:
      • MQTT Control Packets MUST be sent in WebSocket binary data frames. If any other type of data frame is received the recipient MUST close the Network Connection.
      • A single WebSocket data frame can contain multiple or partial MQTT Control Packets.
      The receiver MUST NOT assume that MQTT Control Packets are aligned on WebSocket frame boundaries.
      • The client MUST include "mqtt" in the list of WebSocket Sub Protocols it offers.
      • The WebSocket Sub Protocol name selected and returned by the server MUST be "mqtt".
      • The WebSocket URI used to connect the client and server has no impact on the MQTT protocol.

      3. Add the following bullet point to 7.1.1 (MQTT Server compliance target)
      • Chapter 6 (if MQTT is transported over a WebSocket connection)

      4. Add the following bullet point to 7.1.2 (MQTT Client compliance target)
      • Chapter 6 (if MQTT is transported over a WebSocket connection)
