-- * 'dtIncludeShadowTrails' - Specifies whether to include shadow trails in the response. A shadow trail is the replication in a region of a trail that was created in a different region. The default is true.
--
-- * 'dtTrailNameList' - Specifies a list of trail names, trail ARNs, or both, of the trails to describe. The format of a trail ARN is: @arn:aws:cloudtrail:us-east-1:123456789012:trail/MyTrail@  If an empty list is specified, information for the trail in the current region is returned.     * If an empty list is specified and @IncludeShadowTrails@ is false, then information for all trails in the current region is returned.     * If an empty list is specified and IncludeShadowTrails is null or true, then information for all trails in the current region and any associated shadow trails in other regions is returned.
