Hi

I'm developping a dsl using xtext. Everything goes well, but there is one disadvantage about this, the depenence of xtext. That's why I'm testing Xcore.
My question is very simple. Is it possible to formulate constraints and if so, how do I do that?
This post suggests that this is not possible.

Thanks.

Wouter,

There's no support yet for expressing the logic of a constraint in
Xcore. You can only use Ecore annotations to declare them and then
implement the logic in Java.
