Reliable Messaging

According to ebXML Reliable Messaging proposal, on failure
to deliver, message should be resent.

In this case should the

<Timestamp> element in MessageData be updated to refer to
the new timestamp or the whole message be sent as it is without
changing anything.

If so, MSH should'nt  recreate the digital envelope if requsted
and if non-repudation no re-signing
of the document.
