+ This presence of this extension indicates that an OCSP client can trust a
+ responder for the lifetime of the responder's certificate. CAs issuing
+ such a certificate should realize that a compromise of the responder's key
+ is as serious as the compromise of a CA key used to sign CRLs, at least for
+ the validity period of this certificate. CA's may choose to issue this type
+ of certificate with a very short lifetime and renew it frequently. This
+ extension is only relevant when the certificate is an authorized OCSP
+ responder.
