Appendix A. Change history
The rank priority was expanded to 2 bytes.
00: The extension was originally for the use of Pledges only during
the enrollment/join process. Additional information was desired for
nodes which have already enrolled in order to aid in the joining
(selecting of a parent) of an RPL DAG. The term "join" was realized
to be ambiguous, meaning different things to different groups, and so
the activity where the pledge finds a "Join Proxy" has been named
"enrollment"
-1: This is an evolution of an earlier proposal which provided for
storing an entire IPv6 Router Adverisement in an Informational
Element. It was deemed too general a solution, possibly subject to
mis-use. This proposal restricts the use to just the key pieces of
information required.
