[Openid-specs-ab] Attribute Exchange w/ OpenID Connect?

[Torsten Lodderstedt]

Hi Eve,

thanks for pointing this out. At first glance it seems to be feasable although I honestly don't know whether such an identifier would conflict with the OIDC semantics. 

To give you more context: I'm looking for a way to "just" assert a boolean claim to the RP. The use case, I'm currently investigating, is age verification. The RP wants the OP to attest whether the user is above 18. There is no session between RP and OP and the OP will typically not disclose any further data. I would prefer to realize this without the need to make up an identifier just to fulfill the protocol requirements.

regards,
Torsten.
