As I argued on the DKIM working group list, I think this text is a bad idea. Part of IETF having change control of a specification is having the ability to make changes, and the bar of "necessary to the success of the specification" is way too high for that. Note that I'm not suggesting that the WG shouldn't consider compatibility, merely that it shouldn't be effectively prohibited by charter from making incompatible improvements. -Ekr _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
