 Enables or disables FIPS 140 mode. This replaces the standard
 internal PKCS#11 module with a FIPS-enabled one. It also forces the
-enabled protocols to TLSv1 and disables all ciphers but the
+enabled protocols to TLSv1.2 - TLS v1.0 and disables all ciphers but the
 FIPS ones. You may still select which ciphers you would like
 limited to those that are FIPS-certified. Any non-FIPS that are

+If no NSSProtocol is specified, mod_nss will default to allowing the use of

+minimum protocol allowed, and TLSv1.2 will be set to be the maximum protocol
+allowed.
+ 
+If values for NSSProtocol are specified, mod_nss will set both the minimum
+and the maximum allowed protocols based upon these entries allowing for the
+inclusion of every protocol in-between. For example, if only SSLv3 and TLSv1.2
+are specified, SSLv3, TLSv1.0, TLSv1.1 and TLSv1.2 will all be allowed, as NSS utilizes
+protocol ranges to accept all protocols inclusively
+(TLS 1.2 -&gt;TLS 1.1 -&gt; TLS 1.0 -&gt; SSL 3.0), and does not allow exclusion of any protocols
+in the middle of a range (e. g. - TLS 1.0). 
+ 
+Finally, NSS will always automatically negotiate the use of the strongest
+possible protocol that has been specified which is acceptable to both sides of
+a given connection.
