For example, `RSASSA-PSS` certificate signature algorithm corresponds to multiple signature scheme names and blocking one of those signature scheme with `CertificateSignature` usage directive won't block `RSASSA-PSS` certificate signature because other rsa_pss_* signature schemes still will be allowed. We should direct users to use certificate signature algorithm with `CertificateSignature` usage directive. For example:
