It seems to me that, if you and kre, both of whom have considerable experience reading these sorts of documents, can't agree on what 2460 means and how these bits are to be interpreted, we have a really urgent need for some clarification. Can you get the appropriate AD to sign up for that job and get it assigned to a WG as appropriate? john _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
