+    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.
