--
-- Adds tasks, schedules, and preconditions to the specified pipeline. You
-- can use 'PutPipelineDefinition' to populate a new pipeline.
--
-- 'PutPipelineDefinition' also validates the configuration as it adds it
-- to the pipeline. Changes to the pipeline are saved unless one of the
-- following three validation errors exists in the pipeline.
--
-- 1.  An object is missing a name or identifier field.
-- 2.  A string or reference field is empty.
-- 3.  The number of objects in the pipeline exceeds the maximum allowed
--     objects.
-- 4.  The pipeline is in a FINISHED state.
--
-- Pipeline object definitions are passed to the 'PutPipelineDefinition'
-- action and returned by the GetPipelineDefinition action.
