-- Performs multiple DeleteAttributes operations in a single call, which
-- reduces round trips and latencies. This enables Amazon SimpleDB to
-- optimize requests, which generally yields better throughput.
--
-- The following limitations are enforced for this operation:
--
-- -   1 MB request size
-- -   25 item limit per BatchDeleteAttributes operation
