-- Deletes the specified tags from a file system. If the @DeleteTags@ request includes a tag key that does not exist, Amazon EFS ignores it and doesn't cause an error. For more information about tags and related restrictions, see <http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/cost-alloc-tags.html Tag Restrictions> in the /AWS Billing and Cost Management User Guide/ .
