And from its name, the latter is intended to be discussed and within control of the 6MAN WG. So I don't think that we can say that it "just rely on the AD to keep the "DISCUSS" button pressed." > > In my mind, this should also be a clear indication that the question of header insertion is (to be) within the control of the 6MAN WG. But you may have a different opinion. Maybe my mental algorithm has a bug, but: what's the point of spring working on a document that relies on something that 6man has so far rejected? You spend energy on the document and then... just sit on the I-D to see if 6man adopts voyer-6man-extension-header-insertion? Ship the document to the IESG for them to review? -- I'm lost, sorry. -- Fernando Gont SI6 Networks e-mail: fgont@si6networks.com PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492
