The use of domain-specific languages (DSLs) has been proposed as an approach to cost-effectively develop families of software systems in a restricted application do-main. Domain-specific languages in combination with the accumulated knowledge and experience of previous implementations, can in turn be used to generate new applications with unique sets of requirements. For this reason, DSLs are considered to be an important approach for software reuse. However, the toolset supporting a particular domain-specific language is also domain-specific and is per definition not reusable. Therefore, creating and maintai-ning a DSL requires additional resources that could be even larger than the savings associated with using them. As a solution, different tool frameworks have been proposed to simplify and reduce the cost of developments of DSLs. Developers of tool support for DSLs need to instantiate, customize or configure the framework for a particular DSL. There are different approaches for this. An approach is to use an application pro
