New issue 1412: Add attestation claim to the ID Token in SIOP
https://bitbucket.org/openid/connect/issues/1412/add-attestation-claim-to-the-id-token-in

Kristina Yasuda:

I think we should allow SIOP to communicate “the identity of SIOP/AS“ in the ID Token. We could define an “attestn” \(attestation\) claim that includes identifier of the SIOP provider/AS, and a signature by that provider for integrity protection.
