Standardizing Variability - Challenges and Solutions

Any modeling language can be said to model variability, but our concern is how variability can be expressed generically and thus be standardized on its own and not as an add-on or profile to other languages. In product line engineering feature modeling has been applied to express variants of product models. This paper shows how the Common Variability Language can be designed to enhance feature modeling and automate the production of product models from a product line model.
