-- Removes the specified tags from the specified resources. When you specify a tag key, the action removes both that key and its associated value. The operation succeeds even if you attempt to remove tags from a resource that were already removed. Note the following:
--
--
--     * To remove tags from a resource, you need the necessary permissions for the service that the resource belongs to as well as permissions for removing tags. For more information, see <http://docs.aws.amazon.com/awsconsolehelpdocs/latest/gsg/obtaining-permissions-for-tagging.html Obtaining Permissions for Tagging> in the /AWS Resource Groups and Tag Editor User Guide/ .
--
--     * You can only tag resources that are located in the specified region for the AWS account.
