-- | Changes the visibility timeout of multiple messages. This is a batch version
-- of 'ChangeMessageVisibility'. The result of the action on each message is
-- reported individually in the response. You can send up to 10 'ChangeMessageVisibility' requests with each 'ChangeMessageVisibilityBatch' action.
--
-- Because the batch request can result in a combination of successful and
-- unsuccessful actions, you should check for batch errors even when the call
-- returns an HTTP status code of 200. '&Attribute.1=this'
--
-- '&Attribute.2=that'
