Hi all,

I have two quick questions concerning IANA actions to be done for the OSCORE 
profile:

1) The framework (-params) and the profile are currently conflicting on the 
registration of parameters, and we need to fix that.
In the framework, parameters that are sent from Client to AS (such as req_cnf) 
are registered in the OAuth Parameters Registry as having "Parameter Usage 
Location: token request". The OSCORE profile registers parameters sent from 
Client to RS (such as nonce1) with "Parameter Usage Location: token request". 
The possible "Parameter Usage Location" are "token request" "token response" 
"authorization request" "authorization response" (see 
https://tools.ietf.org/html/rfc6749#section-11.2.1 ). It seems that 
"authorization request/response" are to the Resource Owner, and "token 
request/response" are to the Authorization Server. I think the framework is 
using the right names, but I am not sure what other location to put there, I 
think there is no name for Client-to-RS and RS-to-Client in the registry right 
now.

2) The OSCORE profile defines a new registry, the OSCORE Security Context 
Parameters registry. The question is where to put this registry? My proposal is 
to put it under 
https://www.iana.org/assignments/core-parameters/core-parameters.xhtml . Any 
objections?

Thanks,
Francesca
