This is a reminder that the last call on the deprecation document ends today. In particular, the chairs would like to ensure that the WG agrees on the actual deprecation text in Sections 4 6. There has been few comments on this draft and it cannot proceed unless the chairs can be sure that it

Sections 4 and 6 seem fine. Minor nit in 2.2 which may cause rather than causing. Minor nit in 3, QoS for QOS. Also in 3, in which addresses are not ambiguous and do not have a simple explicit scope. is maybe better left as in which addresses are not ambiguous or maybe change to and thus do

Greg, Backward compatability shouldn't really be a problem. Hosts which are doing RFC2461 Router Discovery will understand RAs with options or bits in them indicating solicitation or completeness, but just not be able to access the improved function. If a host that understands the new
