The discussion of efficient implementation (section 2.2.1) seems vague to me. For example, from the draft: "As new functionality becomes sufficiently well defined to add to endpoints, supporting options can be designed using ordering restrictions and other techniques to ease parsing." What are these ordering restrictions? Does this mean TLVs have (or might eventually have) some defined ordering as to how they can appear in the packet? Would this contradict section 4.3: "Option ordering is not significant". What are "other techniques to ease parsing"?
