This is a great idea.  We currently have a BNF for MapCSS that you started, and that I added some to.  There are some contentious bits in there (for example I require both parentheses and quotes for eval and URL), perhaps working through the bits of this that various people disagree on would be a good idea and coming up with a final, formal syntax that we can all verify that we parse correctly is a good idea.
