Still have many questions to the XEP.

It's needed to add some examples of notifications to be sent:

1. How to determine that the notification is from the past and not the
current notification?
2. Will the server send retracts or node configuration changes
notifications from the past?

Possibly, this "ago" payload should be included in presence
automatically by server since it's not always possible to determine the
value on the client side (I already gave an example when other resource
is becoming online with higher priority and then other resources can't
receive events in case of pubsub and not presence subscription).

Another still uncovered thing is how to determine missed notifications
in the case of connection failures.
