And that makes me feel I have done a half job. However, I also know that starting from scratch it would take me several months to get anywhere near an accurate view (I know from considerable experience with the DTN2 reference implementation and years ago the source code of yacc - now that ages me!) If the wg, doc shepherd and the IESG are happy that the mapping is near enough, so be it. And, sorry, I didn't look at RFC 6569 during my review.. probably shoyuld have done.
