// This action gets an Amazon S3 on Outposts bucket's tags. To get an S3 bucket
// tags, see GetBucketTagging (https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketTagging.html)
// in the Amazon S3 API Reference. Returns the tag set associated with the Outposts
// bucket. For more information, see Using Amazon S3 on Outposts (https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3onOutposts.html)
// in the Amazon S3 User Guide. To use this action, you must have permission to
// perform the GetBucketTagging action. By default, the bucket owner has this
// permission and can grant this permission to others. GetBucketTagging has the
// following special error:
//   - Error code: NoSuchTagSetError
//   - Description: There is no tag set associated with the bucket.
//
// All Amazon S3 on Outposts REST API requests for this action require an
// additional parameter of x-amz-outpost-id to be passed with the request. In
// addition, you must use an S3 on Outposts endpoint hostname prefix instead of
// s3-control . For an example of the request syntax for Amazon S3 on Outposts that
// uses the S3 on Outposts endpoint hostname prefix and the x-amz-outpost-id
// derived by using the access point ARN, see the Examples (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_GetBucketTagging.html#API_control_GetBucketTagging_Examples)
// section. The following actions are related to GetBucketTagging :
//   - PutBucketTagging (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_PutBucketTagging.html)
//   - DeleteBucketTagging (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_DeleteBucketTagging.html)
