-- Describes the ID format settings for your resources on a per-region
-- basis, for example, to view which resource types are enabled for longer
-- IDs. This request only returns information about resource types whose ID
-- formats can be modified; it does not return information about other
-- resource types.
--
-- The following resource types support longer IDs: 'instance' |
-- 'reservation'.
--
-- These settings apply to the IAM user who makes the request; they do not
-- apply to the entire AWS account. By default, an IAM user defaults to the
-- same settings as the root user, unless they explicitly override the
-- settings by running the < ModifyIdFormat> command. Resources created
-- with longer IDs are visible to all IAM users, regardless of these
-- settings and provided that they have permission to use the relevant
-- 'Describe' command for the resource type.
