New issue 1246: Binding of claims and presentation and OP

I would assume the binding is not just to the subject and claim set, but also to the intermediary presenting them \(OP\)

I am not sure if there needs to be a direct binding.

There needs to be two kinds of strong bindings:

1. between the Claim Set from the CP and the OP \(Wallet\) response \(e.g., ID Token\)
2. Between the OP and OP response.

OP and OP Response is bound by the `iss` of the OP response and the signature, and that is given by OIDC Core.

Is there a reason for having direct binding?
