-- Describes attributes of your AWS account. The following are the supported account attributes:
--
-- -   'supported-platforms': Indicates whether your account can launch instances into EC2-Classic and EC2-VPC, or only into EC2-VPC.
--
-- -   'default-vpc': The ID of the default VPC for your account, or 'none'.
--
-- -   'max-instances': The maximum number of On-Demand instances that you can run.
--
-- -   'vpc-max-security-groups-per-interface': The maximum number of security groups that you can assign to a network interface.
--
-- -   'max-elastic-ips': The maximum number of Elastic IP addresses that you can allocate for use with EC2-Classic.
--
-- -   'vpc-max-elastic-ips': The maximum number of Elastic IP addresses that you can allocate for use with EC2-VPC.
