Christian, I'm happy to write up a new draft proposing my changes and go through that process. I'm not happy that my errata have been summarily rejected in less than 24 hours with no time for review.
Consider: hundreds of millions of printers, computers, and mobile devices have been certified and shipped with IPv6 link local support using the IPvFuture format over the last 8 years. It took those 8 years for the IETF to agree on a new format with serious compatibility and interoperability issues with the base IETF standard (STD 66 aka RFC 3986), and my errata against the published RFC have been rejected after less than 24 hours of discussion. How do we notify users of RFC 6874 that there are proposed changes, if not in pending errata? How long will it take to get a new draft approved that fixes the problems in RFC 6874? I certainly hope the answer is not 8 years... On 2013-05-23, at 2:47 AM, Christian Huitema <huit...@microsoft.com> wrote: > Michael, you are asking that the consensus of the WG be reversed.
