Re: further clarifications on M/O flags in rfc2462bis



Dear IPv6 folks, and especially Margaret,

I've not seen any responses to the following proposal:

I'm happy if the silence means agreement, but I suspect others have
been simply too busy for other discussion items to read or comment on
it, since I thought the above proposal could be quite controversial.

So, I made an experimental next revision of the rfc2462bis draft based
on this proposal and put it at:
http://www.jinmei.org/draft-ietf-ipv6-rfc2462bis-07beta1.txt

Specifically,

- this revision does not mention the M/O flags at all.
- this revision does not use the phrase "stateful" (except in change
  logs).  But I replaced the phrase with "DHCPv6" wherever
  appropriate.  For example, this revision says like:

     DAD is performed on all addresses, independent of whether they
     are obtained via stateless autoconfiguration or DHCPv6.
  
  instead of saying "via stateful autoconfiguration".

To make progress, I'd like to be sure if this approach is acceptable.

If you have time, please check the proposal and the experimental next
revision, and let me know your opinion.  If it's okay, I'm then going
to address other comments from Margaret (as the shepherding AD).
