Hi, Les, John and Jeff: Let's reply you all together. In my POV, The standard document should not define solely the protocol extension, but their usages in the network deployment. As I known, almost all the IETF documents following this style. And, before adopting one work, we have often intense discussion for what's their usages. Such discussion in the mail list and statements in the document can certainly assist the reader/user of the document get the essence of the standard, and follow them unambiguously.
Regarding the contents of appendices, as stated in the section, "The Appendix A heuristic to rebuild the topology can normally be used if all links are numbered." I think this can apply almost most of the operator's network, and facilitate the inter-area TE path calculation for central controller, or even for the head-end router that located in one area that different from the tail-end router. Keeping the contents of appendices does not have the negative impact of the protocol extension, it is just one reference for the usage of this extension. One can select not refer to it, if their networks are deployed with large amount of unnumbered links. But for others, the heuristic applies.
