Hi Michael,

I know that the IETF does not work on deadlines. Giri wanted to make the group aware of dependencies.

I have suggested FIDO to request registration of claims in the CWT IANA registry, in a style similar to what you suggest below. I guess there are not many other options given of where we are.

Ciao
Hannes

Right, and yet, the WG can't really guarantee a schedule.
If you read to end, you'll see that I propose a way in which the various industry groups can receive official EAT claim #s from the not-yet-created IANA registry.
That allows them to do interop while EAT specification progresses.
Whether they wish to "release" before EAT has an RFC# or not, is up to them.

Distinct, and yet they are related because FIDO's voucher specification seems to be an EAT rather than a constrained-voucher.
