Re: [802.21] IETF Drafts



This is an interesting suggestion for 802.21 WG to have long-term
control on the IETF requirements.  

Two questions:

- Requirements for other external SDOs may come up after the 802.21
specification becomes a standard.  If that happens, can we do the same
thing in the course of maintaining/updating the specification (e.g.,
in 802.21ma)?

- Do we also need this approach for requirements to other WGs *within
IEEE802*?

Yoshihiro Ohba
