>>>>>>>
>>>>>>> Submitting changes
>>>>>>> ------------------
>>>>>>>
>>>>>>> To submit changes, please reply to this email using ‘REPLY ALL’ as all

>>>>>>> include:
>>>>>>>
>>>>>>> *  your coauthors
>>>>>>>
>>>>>>> *  [e-mail] (the RPC team)
>>>>>>>
>>>>>>> *  other document participants, depending on the stream (e.g.,
>>>>>>>     IETF Stream participants are your working group chairs, the
>>>>>>>     responsible ADs, and the document shepherd).
>>>>>>>
>>>>>>> *  [e-mail], which is a new archival mailing list
>>>>>>>     to preserve AUTH48 conversations; it is not an active discussion
>>>>>>>     list:
>>>>>>>
>>>>>>>    *  More info:
>>>>>>>       https://mailarchive.ietf.org/arch/msg/ietf-announce/yb6lpIGh-

>>>>>>>
>>>>>>>    *  Note: If only absolutely necessary, you may temporarily opt out
>>>>>>>       of the archiving of messages (e.g., to discuss a sensitive matter).
>>>>>>>       If needed, please add a note at the top of the message that you
>>>>>>>       have dropped the address. When the discussion is concluded,
>>>>>>>       [e-mail] will be re-added to the CC list and

>>>>>>>
>>>>>>> OLD:
>>>>>>> old text
>>>>>>>
>>>>>>> NEW:
>>>>>>> new text
>>>>>>>
>>>>>>> You do not need to reply with both an updated XML file and an explicit
>>>>>>> list of changes, as either form is sufficient.
>>>>>>>
>>>>>>> We will ask a stream manager to review and approve any changes that
>>>>> seem
>>>>>>> beyond editorial in nature, e.g., addition of new text, deletion of text,
>>>>>>> and technical changes.  Information about stream managers can be
>>> found
>>>>> in
>>>>>>> the FAQ.  Editorial changes do not require approval from a stream
>>> manager.
