// Deletes tags from a customer managed key (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#customer-cmk)
// . 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 ABAC for
// KMS (https://docs.aws.amazon.com/kms/latest/developerguide/abac.html) 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 Tagging keys (https://docs.aws.amazon.com/kms/latest/developerguide/tagging-keys.html)
// . For general information about tags, including the format and syntax, see
// Tagging Amazon Web Services resources (https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html)
// 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 Key states of KMS
// keys (https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html) 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.
