--
-- Deletes tags from a
-- <https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#customer-cmk customer managed key>.
-- To delete a tag, specify the tag key and the KMS key.
--
-- Tagging or untagging a KMS key can allow or deny permission to the KMS
-- key. For details, see
-- <https://docs.aws.amazon.com/kms/latest/developerguide/abac.html ABAC for KMS>
-- in the /Key Management Service Developer Guide/.
--
-- When it succeeds, the @UntagResource@ operation doesn\'t return any
-- output. Also, if the specified tag key isn\'t found on the KMS key, it
-- doesn\'t throw an exception or return a response. To confirm that the
-- operation worked, use the ListResourceTags operation.
--
-- For information about using tags in KMS, see
-- <https://docs.aws.amazon.com/kms/latest/developerguide/tagging-keys.html Tagging keys>.
-- For general information about tags, including the format and syntax, see
-- <https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html Tagging Amazon Web Services resources>
-- in the /Amazon Web Services General Reference/.
--
-- The KMS key that you use for this operation must be in a compatible key
-- state. For details, see
-- <https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html Key states of KMS keys>
-- in the /Key Management Service Developer Guide/.
--
-- __Cross-account use__: No. You cannot perform this operation on a KMS
-- key in a different Amazon Web Services account.
--
-- __Required permissions__:
-- <https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html kms:UntagResource>
