// This implementation of the DELETE action uses the policy subresource to delete
// the policy of a specified bucket. If you are using an identity other than the
// root user of the Amazon Web Services account that owns the bucket, the calling
// identity must have the DeleteBucketPolicy permissions on the specified bucket
// and belong to the bucket owner's account to use this operation. If you don't
// have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied
// error. If you have the correct permissions, but you're not using an identity
// that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not
// Allowed error. As a security precaution, the root user of the Amazon Web
// Services account that owns a bucket can always use this operation, even if the
// policy explicitly denies the root user the ability to perform this action. For
// more information about bucket policies, see Using Bucket Policies and
// UserPolicies
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/using-iam-policies.html). The
// following operations are related to DeleteBucketPolicy
