It would be great if you could also give an example of the use of the env within the implementation section of the component reference.
Plus in the example you use tags like -{name: Training data} and --train-set, {inputPath: Training data}. Yet later on in the page you reference --train-set, {inputPath: training_data} and training_data=some_task1.outputs['some_data'].
it's not clear if you should use training_data as this works when compiled, or Training data which does not work, and is not easy to see how to use in the pipeline section.
