I would've assumed offline messages to be already covered by the 
following guarantee, just like regular live messages:

>When a message is archived, the server MUST add an <stanza-id/> element 
>as defined in Unique and Stable Stanza IDs (XEP-0359) to the message, 
>which informs the recipient of where and under what ID the message is
