[OASIS Issue Tracker] (MQTT-480) Subscription Options when Retain is optional

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

Ken Borgendale commented on MQTT-480:
-------------------------------------

It is not clear what needs to be said here.  If the server does not support retain, then the retain bit will always be 0 in the incoming message, and no message will ever be sent from a retained source.

Thus the statements here are true regardless of whether or not the server supports retain.
