Subject: [OASIS Issue Tracker] Updated: (MQTT-70) Assumptions for QoS levels 1 and 2 replaced by new Storing State section


     [ http://tools.oasis-open.org/issues/browse/MQTT-70?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Banks updated MQTT-70:
-----------------------------

    Proposal: 
In WD16 

Section 3.2.1.4 Clean Session should refer to Section 4.1 for a description of the limitations of stored state.


In section 4.1 add:

Non normative comment 

Normal operation of the Client of Server may mean that stored state is lost or corrupted because of administrator action,
hardware failure  or software failure. An administrator action could be an automated response to defined conditions. 
These actions might be prompted by resource constraints or for other operational reasons. 
For example the server may determine that based on  external knowledge, a message or messages can no longer be delivered to any current or future client.

> The input specification contains a dedicated section "Assumptions for QoS levels 1 and 2" in summary, this points out that MQTT is only as a reliable as the environment that it is running in. 
> WD08 introduced a section to discuss the storage of state. This should be elaborated to centralize the core messages and the existing 'Assumptions' section removed.
