TAB-1563 - Jacques Durand

We read: “A conformant Server MUST support the use of one or more underlying transport protocols that provide an ordered, lossless, stream of bytes from the Client to Server and Server to Client [MQTT-7.1.1-1]. However, conformance does not depend on it supporting any specific transport protocols. A Server MAY support any of the transport protocols listed in section 4.2, or any other transport protocol that meets the requirements of section 4.2.” But that will not help an end-user to know if its conforming Server will be able to communicate with a conforming Client. For this, the conformance clause should be “parameterized” – see “5.5 variable conformance clauses” in http://docs.oasis-
