Discuss a way to express binding claims using IDA syntax

[Daniel Fett]

There is a discussion connected to the SD-JWT VC draft on how claims can be expressed in a credential that were checked by the issuer of the credential and can be used for binding the credential to another credential.

Please find the discussion at https://github.com/oauth-wg/oauth-sd-jwt-vc/issues/145

One approach to express claims suitable for binding is this:

{
  "title" : "Master of Science in Physics",
  "grade" : "excellent",
  "given_name" : "Erika",
  "family_name" : "Mustermann",
  "date_of_birth" : "1970-01-01",
  "cbb" : [ "given_name", "family_name", "date_of_birth" ]
}

This WG might be interested in figuring out if there is a use for IDA syntax here.
