The problem is that all of the practical (i.e., not constructed just for the document) examples we have, especially with the advice to not use these group addresses except under special circumstances, are associated with EAI. So, as soon as one says something equivalent to "summarize the benefit and provide use cases" one either becomes dependent on EAI for examples (which is not what we usually mean by "dependent") or is constructing works of fancy or speculation. The other approach --and the one I think Ned is advocating although he can speak for himself-- is to make this change primarily because embedding the prohibition on using groups in backward-pointing addresses in the syntax has outlived its usefulness if, indeed, it was ever wise. Instead, we end up with the syntax restriction eliminated and rather general use/applicability advice. It seems to me that ought to be sufficient. best, john _______________________________________________ Gen-art mailing list Gen-art@ietf.org https://www.ietf.org/mailman/listinfo/gen-art
