-- The following lists the names, descriptions, and values of the special
-- request parameters the 'SetQueueAttributes' action uses:
--
-- 'DelaySeconds' - The time in seconds that the delivery of all messages in
-- the queue will be delayed. An integer from 0 to 900 (15 minutes). The default
-- for this attribute is 0 (zero).  'MaximumMessageSize' - The limit of how many
-- bytes a message can contain before Amazon SQS rejects it. An integer from
-- 1024 bytes (1 KiB) up to 262144 bytes (256 KiB). The default for this
-- attribute is 262144 (256 KiB).  'MessageRetentionPeriod' - The number of
-- seconds Amazon SQS retains a message. Integer representing seconds, from 60
-- (1 minute) to 1209600 (14 days). The default for this attribute is 345600 (4
-- days).  'Policy' - The queue's policy. A valid form-url-encoded policy. For
-- more information about policy structure, see <http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/BasicStructure.html Basic Policy Structure> in the /Amazon SQS Developer Guide/. For more information about form-url-encoding, see <http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.1 http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.1>.  'ReceiveMessageWaitTimeSeconds' - The time for which a ReceiveMessage call
-- will wait for a message to arrive. An integer from 0 to 20 (seconds). The
-- default for this attribute is 0.   'VisibilityTimeout' - The visibility timeout
-- for the queue. An integer from 0 to 43200 (12 hours). The default for this
-- attribute is 30. For more information about visibility timeout, see
-- Visibility Timeout in the /Amazon SQS Developer Guide/.  'RedrivePolicy' - The
-- parameters for dead letter queue functionality of the source queue. For more
-- information about RedrivePolicy and dead letter queues, see Using Amazon SQS
-- Dead Letter Queues in the /Amazon SQS Developer Guide/.
