Hi,

I've already posted some questions in the last weeks where I asked for
help on how to implement a grammer and editor for CSS 2.1.

I got quite far already but now I'm hitting a road block because my real
target is to write a CSS-Editor for JavaFX which uses an extended
CSS-Syntax for defining gradients as part of the CSS [1].

The problem is that their gradient definition is not vaild when you look
at the BNF for CSS[2] I translated to xtext [3] because of their usage
of '('...')'.

While I could say that they've speced their gradient definition
inappropriately (and I'm quite sure I'm right and filed a bug against
them) - does anybody have an idea how I could fix the problem in my grammer?

Tom
