[Openid-specs-ab] Definition of required and optional claims? Handling?

[Mike Jones]

If a required claim isn't available, that's an error.  (It's not for optional claims.)  But looking at the list of errors in 2.1.4 http://openid.net/specs/openid-connect-messages-1_0-09.html#anchor8 we haven't defined an error for that case.  I suspect we should define one like "required_claim_unavailable".

What are other's thoughts?

Several places in spec (mostly on the OpenID request object) mention "required claim" and "optional claim". I was kind of wondering what exactly these are until I read section 5.1.3 on handling "acr" claim requests.

http://openid.net/specs/openid-connect-messages-1_0-09.html#req.obj.veri

Would it make sense to define "required claim" and "optional claim" in a separate section? Also their handling, if it can be generalised?

Right now I'm not sure about the difference between required and optional UserInfo claim requests. How is a required UserInfo claim request to be handled if the data isn't available on the server?

Cheers,

Vladimir
