55: When a client sends a PUBLISH to a server,

57: the server should hold on to the message after it has been
58: delivered to the current subscribers.
59: When a new subscription is established on a topic,
60: the last retained message on that topic should be sent to
61: the subscriber with the Retain flag set.
62: If there is no retained message, nothing is sent
63: This is useful where publishers send messages on a
64: "report by exception" basis, where it might be some time between messages.
65: This allows new subscribers to instantly receive data with the retained,
66: or Last Known Good, value.
67:
68: When a server sends a PUBLISH to a client as a result of
69: a subscription that already existed when the original PUBLISH arrived,
70: the Retain flag should not be set, regardless of the Retain flag
71: of the original PUBLISH. This allows a client to distinguish messages
72: that are being received because they were retained and those
73: that are being received "live".
74:
75: Retained messages should be kept over restarts of the server.
76: A server may delete a retained message if it receives a message
77: with a zero-length payload and the Retain flag set on the same topic. */
