[OASIS Issue Tracker] (MQTT-554) Should QoS 0 messages be held on a message queue during sleep cycle

[ https://issues.oasis-open.org/browse/MQTT-554?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Simon Johnson updated MQTT-554:
-------------------------------
    Proposal: 
*6.14 Support of sleeping clients* should be amended to read;

Sleeping clients are clients residing on (battery-operated) devices that want to save as much energy as possible. These devices need to enter a sleep mode whenever they are not active, and will wake up whenever they have data to send or to receive. The server/gateway needs to be aware of the sleeping state of these clients and will buffer messages destined to them for later delivery when they wake up. *The gateway may choose to buffer messages of all quality of service levels whilst the client is sleeping.*
