As discussed on the 20-Mar-23 working group call, we don't need to do this for the proposed Implementer's Draft.

@decentralgabe please let us know when would be the right time to make this change.

[decentralgabe]

I believe it's the right time to make this change, since the VCDM v2 is in CR. Should the examples be updated to include both v1.1 and v2.0 or only v2.0?

[Sakurann]

I originally opened that issue, but I do not believe we should overwrite v.1.1 text/examples in OID4VP as there are still implementations who use VCDM v1.1 as defined currently.
if we want to support v2.0, we could add a separate section on VCDM 2.0, but we should discuss in a WG first.

@Sakurann this is a fine recommendation. Given the discussion in the PR & mailing list, my perspective is that doing either/both would be much simpler without presentation exchange.

I'd know that's discussion for another issue, but I'm curious if you think that's a possibility.
