Yes, went backed and looked at your slides again. Makes sense. Definitely a use case to support.

When talking in terms of roles, I definitely think that Verifier B is just co-located with the RP, not part of the RP.

I’m not sure if we should consider Verifier A + Verifier B a composite Verifier or not. In my comments above I clearly asserted that all the verifiers (in a composite verifier) must have run before there is any AR. By that criteria it is definitely not, but maybe that definition is too strict? 

I’m also not sure what we should call the intermediate results between Verifier in a composite verifier. By my criteria above it can’t be AR-Augmented Evidence, but again, maybe that criteria is too strict.

Ironic in a way — I want to forward/passthrough Evidence in Results, you are forwarding/passingthrough Results in Evidence :-)
