// container for accounts that enables you to organize your accounts to apply
// policies according to your business requirements. The number of levels deep that
// you can nest OUs is dependent upon the policy types enabled for that root. For
// service control policies, the limit is five. For more information about OUs, see
// Managing Organizational Units (https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_ous.html)
