We feel however that shadows should be considered a notion beyond any specific programming languages, so that they can as well be integrated in model-driven software engineering. Therefore we introduce Shadows-UML, an UML extension, that would help to push forward the convergence between model-driven and agile methodologies.enText/Conference Paper1617-5468
