-- Creates a new version of the specified AWS IoT policy. To update a
-- policy, create a new policy version. A managed policy can have up to
-- five versions. If the policy has five versions, you must delete an
-- existing version using DeletePolicyVersion before you create a new
-- version.
--
-- Optionally, you can set the new version as the policy\'s default
-- version. The default version is the operative version; that is, the
-- version that is in effect for the certificates that the policy is
-- attached to.
