Kris:

thank you for your comment. You are missing the "JavaScript" piece in your picture. At the end of the day (and as your picture shows it) it is not a visual-DSL vs textual-DSL problem (they are isomorphic), the question (and the problem) is that there is a continuum between code and models, a model without "implementation" elements is not that useful (imagine HTML without JavaScript...).

Then the question is how do you generally add implementation elements to a metamodel and how do you infer the syntax in relation to the metamodel.

JavaScript was added "behind" the model, that's a (simplistic) strategy (Microsoft is using that strategy a lot), but that's not very modular.

If you are really serious about creating a "pragmatic" framework that offers a continuum between code and model, you cannot avoid the M3 layer (IMHO).
