Re: [Rats] New Version Notification - draft-ietf-rats-architecture-20.txt

Hi!

Thanks for clarifying text in -20 whose motivation was discussed at discussed at IETF 113.

Section 3
As explained in Section 5, artifacts are defined by which roles	
produce them or consume them.  In some protocol instantiations, other	
roles may cache and forward artifacts as opaque data, to one or more	
entities implementing the consuming role. 

Saying that things may cache and forward if they are already consuming doesn't square with the later text:

Section 5.1.  "The Attester does not consume the Attestation Result, but might cache it."

I think caching and forwarding needs to be independent of whether they are consumers.  I recommend a bit more text:

NEW (roughly)

As explained in Section 4, there are a variety of roles in the RATS architecture and they are defined by a unique combination of artifacts they produce and consume. Conversely, artifacts are also defined by the roles that produce or consume them.  To produce an artifact means that a given role introduces it into the RATS architecture.  To consume an artifact means that a given role has responsibility for processing it in the RATS architecture.  Roles also have the ability to perform additional actions such caching or forwarding artifacts as opaque data.  As depicted in Section 5, these additional actions can be performed by several roles.
