   <p>A single message may be corrected multiple times by subsequent edits.</p>
   <p>A correction MUST only be allowed when both the original message and correction are received from the same full-JID.</p>
   <p>While it's not possible to prevent this protocol from being used in such a way, it is not intended that it provides a way to continue expanding a previous message indefinitely and clients, in as much as it is sensible, should present use of this extension only for correction rather than for providing a continuous stream, for which &xep0301; can be used instead.</p>
+  <p>If the same message is to be corrected several times, the id of the original message is used in each case (e.g. If a message of id 1 is corrected by a message of id 2, a subsequent correction should correct 1, not 2).</p>
   <p>Correction MUST only be used to change the details of a stanza (e.g. the message body) and not to change the nature of the stanza (e.g. correction MUST NOT be used to turn a chat message into a pubsub notification)</p>
   <p>While it is possible to use this protocol to correct messages older than the most recent received from a full JID, such use is out of scope for this document and support for this SHOULD NOT be assumed without further negotiation.</p>
