Detailed Description:

observation 1

Section 4.1.10 Credential Revocation says,

Digital Wallet Providers SHALL implement the OCI Directory Service (LDAP)-based mechanism for determining if a Verifiable Credential has been revoked (vc-status-2021-ldap).

This is not precise, as the issuer needs to run LDAP servers, the wallet just needs to be able to call them.
Suggest to reword to sth like,

wallet providers shall implement API calls to the LDAP server of the issuer and check the revocation status

observation 2

I'd also remove the intro sentence, as that's hypothetical and not relevant for audits or implementers. They only need to know what applies NOW.

OCI can potentially support multiple methods for communicating when a Credential has been revoked.

observation 3

Further, the para ends with,

Credential Issuer and Digital Identity providers SHALL implement LDAPS, which is LDAP secured by communication over Transport Layer Security (TLS) protocol.

The CI criteria do not belong in the wallet conformance document.
