The Parameter Details include the maximum value, minimum value, and default value for the validity period applicable to a certificate. These values are used only when a certificate request does not match any predicates in the Predicate Details section.
The Predicate Details would include any predicates to be matched against certificate requests, and if a match occurred, the corresponding values specified with the predicate would be used for that certificate's validity period.
In this illustration, no predicates are shown.
