WHO SVC "Smart Vaccination Certificate" interim guidance

Hi team

https://cdn.who.int/media/docs/default-source/documents/interim-guidance-svc_20210319_final.pdf

The interim guidance from the WHO on smart vaccination certificates.

   - The document details the semantic payload (data model and codes) for a
   certificate - which makes sense.
   - No mention of W3C Verifiable credentials in there.  looks like more of
   a traditional PKI chain of trust architecture.
   - On the other hand the verification protocol description is quite
   abstracted from specific technologies so it may be possible to implement a
   VC based solution within a member country and still claim WHO SVC
   compliance - although I havent worked through all the sequence diagrams /
   architecture diagrams to confirm whether or not a W3C VC solution could be
   "compliant".

Has anyone in this group had any involvement in this and does anyone have a
more informed opinion about whether a W3C VC based solution using a JSON-LD
version of the semantic payload could be considered compliant with the
standard?

cheers,
steve
