Pascal: Hi! I see Elwyn’s point, and agree that it might be nice to see that in the registry. However, your point about the description being from the RPL perspective keeps me from thinking that it is a necessary addition. If I remember correctly, not all the status codes may be considered the same way in RPL when compared to ND. Also, there’s no E flag used in ND. I don’t think we should make the extra change to the registry in this document. Thanks! Alvaro.

Since this draft 'needs' the extra information I personally wouldn't see a problem in asking for the extra column. It doesn't break anythng 6LoWPAN are doing AFAICS. Anyway that's not my call... ask your AD. What do you think? Pascal
