Fine with me :)
Might want to add some more comments for readability and better IDE devX.

nit: it may be better to keep/group related constants in an object rather than having a bunch of individual consts.

Proposed Changes
Add MQTT as a
Messageformat.Description
This commit adds
MQTTto the supported transport protocols by adding aBindingand theMQTTMessage<T>type, extending the baseMessagetype, adding the MQTT fields forpayload,PUBLISHandUser Properties. Thepayloadfield directly maps toMessage#body, whileUser Propertiesroughly maps toMessage#headers, even though the properties here are not formatted with ace-prefix like other transport protocols. This is per the spec. See: https://github.com/cloudevents/spec/blob/v1.0.1/mqtt-protocol-binding.md. ThePUBLISHproperty is there primarily to support the"Content type"and perhaps should be typed better. Feedback welcome.
