// Returns metadata about all versions of the objects in a bucket. You can also use
// request parameters as selection criteria to return metadata about a subset of
// all the object versions. To use this operation, you must have permissions to
// perform the s3:ListBucketVersions action. Be aware of the name difference. A 200
// OK response can contain valid or invalid XML. Make sure to design your
// application to parse the contents of the response and handle it appropriately.
// To use this operation, you must have READ access to the bucket. This action is
// not supported by Amazon S3 on Outposts. The following operations are related to
// ListObjectVersions:

// * ListObjectsV2
// (https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html)
