          :type versioning: bool
          :param versioning: A boolean indicating whether version is
                             enabled (True) or disabled (False).
  
          :type mfa_delete: bool
          :param mfa_delete: A boolean indicating whether the Multi-Factor
                             Authentication Delete feature is enabled (True)
                             or disabled (False).  If mfa_delete is enabled
                             then all Delete operations will require the
                             token from your MFA device to be passed in
                             the request.
  
          :type mfa_token: tuple or list of strings
          :param mfa_token: A tuple or list consisting of the serial number
                            from the MFA device and the current value of
                            the six-digit token associated with the device.
                            This value is required when you are changing
                            the status of the MfaDelete property of
                            the bucket.
