draft-worley-references-01 contains a section comparing its proposal
with the other two session identification drafts.
(http://tools.ietf.org/html/draft-worley-references-01#section-5)  The
overlap with draft-loreto-sipping-dialog-correlation-01 is rather small,
but draft-kaplan-sip-session-id-00 could be incorporated into the system
of draft-worley-references-01.
