-- | 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. &amp;Attribute.1=this
-- &amp;Attribute.2=that.
