-- Deletes up to ten messages from the specified queue. This is a batch
-- version of DeleteMessage. The result of the delete action on each
-- message is reported individually in the response.
--
-- 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.
--
-- Some API actions take lists of parameters. These lists are specified
-- using the 'param.n' notation. Values of 'n' are integers starting from
-- 1. For example, a parameter list with two elements looks like this:
--
-- '&Attribute.1=this'
--
-- '&Attribute.2=that'
