+
+<usage>
+<p>This option enables OCSP validation of the client certificate
+chain. If this option is enabled, certificates in the client's
+certificate chain will be validated against an OCSP responder after
+normal verification (including CRL checks) have taken place.</p>
+
+<p>The OCSP responder used is either extracted from the certificate
+itself, or derived by configuration; see the
+<directive module="mod_ssl">SSLOCSPDefaultResponder</directive> and
+<directive module="mod_ssl">SSLOCSPOverrideResponder</directive>
+directives.</p>
