-- Resets an attribute of an instance to its default value. To reset the
-- 'kernel' or 'ramdisk', the instance must be in a stopped state. To reset
-- the 'SourceDestCheck', the instance can be either running or stopped.
--
-- The 'SourceDestCheck' attribute controls whether source\/destination
-- checking is enabled. The default value is 'true', which means checking
-- is enabled. This value must be 'false' for a NAT instance to perform
-- NAT. For more information, see
-- <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_NAT_Instance.html NAT Instances>
-- in the /Amazon Virtual Private Cloud User Guide/.
