            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.
            Note
            If one or more trail names are specified, information is returned only if the names match the names of trails belonging only to the current region. To return information about a trail in another region, you must specify its trail ARN.
