    The container element for object ownership for a bucket's ownership controls.

    BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if
    the objects are uploaded with the <code>bucket-owner-full-control</code> canned ACL.
</p>
<p>
    ObjectWriter - The uploading account will own the object if the object is uploaded with
    the <code>bucket-owner-full-control</code> canned ACL.
</p>
<p>
    BucketOwnerEnforced - ACLs are disabled, and the bucket owner owns all the objects in the bucket.
    Objects can only be uploaded to the bucket if they have no ACL or the
    <code>bucket-owner-full-control</code> canned ACL.
