How to use the W-EnsembleSelection operator?

Question

I would like to use the W-EnsembleSelection operator in order to combine different regression models. This operator has a parameter L which "specifies the Model Library File, continuing the list of all models". This parameter seems to be the reason why I don't get it to work.

Does anybody know what to do if, for example, I want to put a SimpleLinearRegression and a LibSVMLearner (for SV-regression) in the W-EnsembleSelection?

Thank you for your help!

I saved the list as ensemble.model.xml In that file there is -
