Peter Niblett updated MQTT-143:
-------------------------------

    Proposal: Delete this sentence, and the corresponding one in 4.3.3 as part of the general tidyup of 4.3 normative text being carried out in mqtt-152

>                 Key: MQTT-143
>                 URL: https://tools.oasis-open.org/issues/browse/MQTT-143
>             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.1.1
>         Environment: Normative
>            Reporter: Patrick Durusau

> In 4.3.2:
> "A Server MUST store the message in accordance to its QoS properties and ensure onward delivery to applicable subscribers [MQTT-4.3.2-2]"
> This requirement is rather vague - should be more precise, as the rules for storing a message are nowhere explicitly stated.
> Isn't storage rules not just depending on QoS: but also depending on  RETAIN flag?
> Also the statement  seems to contradict MQTT-4.1.0.1 that states that any(?) "data" must be stored for the life of a connection.
