// GetObjectTaggingRequest returns a request value for making API operation for
// Amazon Simple Storage Service.
//
// Returns the tag-set of an object. You send the GET request against the tagging
// subresource associated with the object.
//
// To use this operation, you must have permission to perform the s3:GetObjectTagging
// action. By default, the GET operation returns information about current version
// of an object. For a versioned bucket, you can have multiple versions of an
// object in your bucket. To retrieve tags of any other version, use the versionId
// query parameter. You also need permission for the s3:GetObjectVersionTagging
// action.
//
// By default, the bucket owner has this permission and can grant this permission
// to others.
//
// For information about the Amazon S3 object tagging feature, see Object Tagging
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/object-tagging.html).
