Discussing RFC 5291 procedures for the immediate/defer flag is unnecessary in new ORF documents.

From Section 6:

  During a single BGP session, the speaker MAY pass multiple ORF
   entries to the peer.

   After a BGP speaker makes changes to the ORF entries previously sent
   to a peer, the speaker MUST send to the peer the updated ORF entries
   with either (a) When-to-refresh set to IMMEDIATE, or (b) When-to-
   refresh set to DEFER followed by a plain ROUTE-REFRESH message.  The
   latter MUST be used by the speaker when there are other policy
   changes (in addition to the ORF entries) that require the peer to
   re-advertise all the routes.
The intent of the flags is "more is coming" and "I'm done, please proceed with the refresh".
