Hi Miguel

Thanks for the registration and sorry for my slow response.

The registration is fine in terms of provided parameters although the reference to the OpenID Connection specification confuses me a little bit.

I do, however, have a question regarding the nfv_token parameter. I looked at your spec and, if I understand it correctly, you want to return a proof-of-possession access token in the token response. What I don't understand is why you need a new parameter for carrying the nfv_token. You could just return the PoP token in the access_token parameter. The profiling of the content of the access token, as you are doing in Section 5.5, is OK.

From a quick look at your specification it appears that you have to register many other parameters with IANA as well, for example the client meta-data and the AS discovery meta-data. Am I wrong?

Ciao
Hannes
