Define how OID4VP parameters are carried over to VPs normatively #171

There is an implicit understanding that parameters such as nonce, client_id and client_id_scheme are used in VPs but we don't have explicit language how this is done for specific format identifiers.

I propose to add language that define that profiles must describe how. For profiles defined by OID4VP, this language should be added to the credential format sections.

I missed the notes in the credential profiles section that says how this is done. I guess I got confused because the text is below an example and included in a note. I'm wondering whether normative language would make sense similar to what we did for SD-JWT VC and verifier metadata: https://openid.github.io/OpenID4VP/openid-4-verifiable-presentations-wg-draft.html#appendix-A.4.2. It would certainly help interoperability. Thoughts?

what kind of language are you thinking for other credential formats, ie mdocs and vcdm?
