Yeah. ::outside is pretty novel also, from a CSS perspective. That might 
well be why it hasn't gone anywhere since I originally specced it in early 
2002/2003. I think it'd be great for it to be implemented, but we're more 
likely to get there by pushing ::outside than trying to push a special 
case version of it, I think.
