Dave asked about:

2.1. Static attestations
 A static attestation says something about the platform on which the
 code is running.

saying:
  Commented [DT5]: In what sense is this ‘static’? It can
  be updated at any time, and so can a policy as to whether a
  platform is considered compliant or not.

and I gotta say, I don't know.

I'm sorry about my consistent attestion vs attestation!

I'll find an appropriate draft to point a reference at on next edit.

Is a reference to the conference itself the right thing?
How is this different from the media and DRM situation?

This one seems rather abstract to me.

I got another revision posted with your changes:

https://www.ietf.org/rfcdiff?url1=draft-richardson-rats-usecases-03&url2=draft-richardson-rats-usecases-04

I've edited your suggested text slightly, but I didn't think I'd have to
chase the references better.
