<p>An archiving service MAY replace the contents of a message that was retracted due to moderation with a 'tombstone' similar to the one described in &xep0424;.</p>
<p>The archiving service replaces the message with a &lt;moderated/&gt; element which contains a &lt;retracted/&gt; element. The &lt;moderated/&gt; element MUST include a 'by' attribute specifying the JID of the moderating entity. The &lt;retracted/&gt; element SHOULD contain a 'from' attribute which points to the JID of the author of the retracted message.</p>
<p>If the message was sent in a semi-anonymous MUC, the occupant id from &xep0421; needs to be included for the moderator and the message author in the &lt;moderated/&gt; and &lt;retracted/&gt; elements respectively. </p>
<p>A &xep0313; service MAY replace the contents of a message, that was retracted due to moderation, with a 'tombstone' similar to the one described in &xep0424;.</p>
<p>The archiving service replaces the message contents (i.e. the &lt;body/&gt; and any related elements which might leak information about the original message) with a &lt;moderated/&gt; element which in turn contains a &lt;retracted/&gt; element. The &lt;moderated/&gt; element MUST have a 'by' attribute specifying the JID of the moderating entity.</p>
