Well, maybe other people see what you are doing beyond what I can and you can have these discussion anyhow.

One of the things that again confuse me is the "we have extended ubiquitous language"... The UL is a collection of exactly defined words, on which developers and the domain experts are in total agreement on their meaning, so they can communicate with less chance of misunderstandings. This language is suppose to be a natural language, easily readable by domain experts (which often are non IT people), so it is not supposed to be a programming style language like the DSL and it cannot be "extended".
