}The holder creates a dif/credential-manifest/application@v1.0 attachment which includes a VP that is a CredentialApplication. This includes a credential_application that links to the manifest from the offer message and the proof types they would be happy to receive. It also includes a presentation_submission that links to the presentation definition from the offer message. The descriptor_map describes where to find the challenge.. not sure if I got the JSONPath right for that. The verifiableCredential is the same one that the offer included however the holder has filled in the credentialSubject.id. Interestingly I had to also add a proof on there to make it a VC I think? Finally, that proof on the VP includes the challenge for DID Authentication.

What we need to work out here are commonalities and where do we need to adjust according to the spec of JFF. Meaning that we find a shared JSON structure inside the attachement or where do we put the layer
We also have to understand what does the attachement here offer of functionality
