Consider a situation where a user sends a message that may be deemed inappropriate by a groupchat moderator. The groupchat service will append a &xep0359; stanza ID to the message before relaying it to all participants..
If the moderator is allowed to moderate the message, the groupchat service will send a message stanza to all participants (including the moderator), indicating that the message has been retracted and by whom.
-This message will use &xep0422; to indicate that it applies to the moderated message, by referring to its XEP-0359 origin ID.
+This message will use &xep0422; to indicate that it applies to the moderated message, by referring to its XEP-0359 Stanza ID.
In case the message could for some reason not be retracted, the grouchat service responds with an IQ stanza of type error.
An archiving service MAY replace the contents of a message that was retracted due to moderation with a 'tombstone' similar to the one described in &xep0424;.
-The archiving service replaces the message with a <moderated/> element which contains a <retracted/> element. The <moderated/> element MUST include a 'by' attribute specifying the JID of the moderating entity. The <retracted/> element SHOULD contain a 'from' attribute which points to the JID of the author of the retracted message.
-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 <moderated/> and <retracted/> elements respectively.
+A &xep0313; service MAY replace the contents of a message, that was retracted due to moderation, with a 'tombstone' similar to the one described in &xep0424;.
+The archiving service replaces the message contents (i.e. the <body/> and any related elements which might leak information about the original message) with a <moderated/> element which in turn contains a <retracted/> element. The <moderated/> element MUST have a 'by' attribute specifying the JID of the moderating entity.
