I would prefer for RATS WG to continue with the current architecture draft (draft-birkholz-rats-architecture-02) and develop it further for many reasons (including that so much work and time has been put into this architecture draft).

Dave's new draft (draft-thaler-rats-architecture-00) well written, and identifies a very good problem scenario being solved.

One way to solve this dilemma of drafts is to use the term "profiles" for more specific/narrower problems being solved.

So if draft-birkholz could be the top level architecture document, then draft-thaler could be a profile that addresses a given problem scenario (e.g. network endpoint assessment).

This profiling approach is also used with great success in other WGs (e.g. OAuth WG with OAuth and UMA profile), and also in other standard organizations (e.g. SAML-WebSSO is a profile of SAML-core).

This would also allow other profile drafts in RATS to be developed beyond network endpoint assessment.
