To address this issue, I've added a new implementation note to my
working copy of JEP-0060:
12.10 Notification of Subscription Denial or Cancellation
Various actions and events may result in the denial of a subscription
request (see the Manage Subscription Requests use case) or the
cancellation of an existing subscription (e.g., if the underlying
presence subscription is cancelled and the node is of type "presence" or
the entity is moved to a new roster group and the node is of type
"roster"). When this occurs, a service SHOULD send a message to the
(former or denied) subscriber informing it of the cancellation. The
message MUST be of the following form:
Example 189. Unsubscription notification
to='francisco at denmark.lit'
jid='francisco at denmark.lit'/>
If the service has knowledge of the (former or denied) subscriber's
presence, it SHOULD send the message to all of the subscriber's
resources; if not, it MUST send the message to the subscriber's
affiliated JID (usually a bare JID).
This JEP now has 196 examples. Convince me to add a few more and we'll
be over 200. Yes, we put the example in example.com! ;-)
