-- * 'dFilters' - Filters applied to the certificate described in the form of key-value pairs.

-- * 'dMarker' - An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by @MaxRecords@ .
--
-- * 'dMaxRecords' - The maximum number of records to include in the response. If more records exist than the specified @MaxRecords@ value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.  Default: 10
