Why not just make a second CSS language grammar out of it? This way the CSS purists don't need to worry and it still is easily availably to those who are interested in it. Just add a help file describing what the point of it is plus some pointers to other references on uses and applications…?
This is certainly possible and I may do it if necessary. The reason I'd prefer not to is that I would then need to keep up with all changes to the CSS language definition to keep my version up to date. Even if I take the time to script it, it's still a bit of a hassle. The patch I have only adds about 10 lines to the CSS bundle and anyone not using the features would never know it was there. In any case, I'll create a patch file and send it to the list and then let the powers that be decide... :)
