-- Retrieves the specified inline policy document that is embedded with the specified IAM role.
--
--
-- An IAM role can also have managed policies attached to it. To retrieve a managed policy document that is attached to a role, use 'GetPolicy' to determine the policy's default version, then use 'GetPolicyVersion' to retrieve the policy document.
