<p>
Specifies whether the trail applies only to the current Region or to all Regions. The default is false. If the
trail exists only in the current Region and this value is set to true, shadow trails (replications of the trail)
will be created in the other Regions. If the trail exists in all Regions and this value is set to false, the
trail will remain in the Region where it was created, and its shadow trails in other Regions will be deleted. As
a best practice, consider using trails that log events in all Regions.
