Re: Working Group Last Call: Applicability Statement of NSIS Protocols in Mobile Environments

Hi,

Are this really an applicability statement in the RFC 2026 sense? This
document is not intended to SPECIFY how you would use NSIS for mobility
signaling.

From Section 3.2 of RFC 2026:
>    An Applicability Statement specifies how, and under what
>    circumstances, one or more TSs may be applied to support a particular
>    Internet capability.  An AS may specify uses for TSs that are not
>    Internet Standards, as discussed in Section 7.
> 
>    An AS identifies the relevant TSs and the specific way in which they
>    are to be combined, and may also specify particular values or ranges
>    of TS parameters or subfunctions of a TS protocol that must be
>    implemented.  An AS also specifies the circumstances in which the use
>    of a particular TS is required, recommended, or elective (see section
>    3.3).
>
>    An AS may describe particular methods of using a TS in a restricted
>    "domain of applicability", such as Internet routers, terminal
>    servers, Internet systems that interface to Ethernets, or datagram-
>    based database servers.
> 
>    The broadest type of AS is a comprehensive conformance specification,
>    commonly called a "requirements document", for a particular class of
>    Internet systems, such as Internet routers or Internet hosts.
> 
>    An AS may not have a higher maturity level in the standards track
>    than any standards-track TS on which the AS relies (see section 4.1).
>    For example, a TS at Draft Standard level may be referenced by an AS
>    at the Proposed Standard or Draft Standard level, but not by an AS at
>    the Standard level.



It might be worth changing the title of the document to avoid having
people thinking it is a AS. Remove Statement and add a The before
applicability.

Cheers
