Re: [Anima] I-D Action: draft-ietf-anima-grasp-api-09.txt

Well, nobody has commented on the open issues below. I have inserted proposed resolutions below. If nobody objects in the next few days, we'll make those minor changes, and make one more minor fix to the references.

Proposed resolution: make this change. The word "nonce" might give a false impression of security.

> 2) The second one is more subtle. In the discover() there is an option to delete stale entries from the discovery cache, via the minimum_TTL parameter. Two reviewers noted that this will affect all ASAs interested in the same objective, not just the ASA using minimum_TTL. Is that OK? If not, we'd reword it such that discover() ignores stale entries rather than deleting them. Should we make this change?

Proposed resolution: no change. If one ASA believes that a discovered locator is stale, it seems reasonable to make it stale for all other ASAs too.

Best wishes for the New Year to everyone.
