## 7.3 OCSP profile
If an OCSP response is for a Root CA or Subordinate CA Certificate, including Cross-Certified Subordinate CA Certificates, and that certificate has been revoked, then the `revocationReason` field within the `RevokedInfo` of the `CertStatus` MUST be present.
The `CRLReason` indicated MUST contain a value permitted for CRLs, as specified in [Section 7.2.2](#722-crl-and-crl-entry-extensions).
