RFC 3923 comes to my mind:

with its <e2e> message body. Unless those are specifically intended to
not be stored offline because of encryption properties (such as
forward secrecy).

But I was wondering whether this could be generalised a bit more to perhaps suggest that any message of type 'chat' with an empty body should not be stored offline. xep-0334 could then be extended to allow a client to hint that a message should be stored offline
