Section 10. review and omitt if necessary RPL re-statements

While I haven't provided a detailed review of the remainder of section 10 because I don't think it's necessary for the goals of this document, it appears to me that much of section 10 is a restatement of the RPL specification from RFC 6550 and should, therefore, be omitted (if RPL is retained as a part of this recommendation).
