-- Lists and describes the versions of a model in an Amazon Rekognition
-- Custom Labels project. You can specify up to 10 model versions in
-- @ProjectVersionArns@. If you don\'t specify a value, descriptions for
-- all model versions in the project are returned.
--
-- This operation requires permissions to perform the
-- @rekognition:DescribeProjectVersions@ action.
--
-- This operation returns paginated results.
