[Mapcss] Associating overpass result sets with MapCSS, was: Re: Example for "set"

I don’t know if it will work, but the way I have been thinking is like this:

way[highway=residential][!surface] {
	set:	surface=unpaved;
}
way[highway=motorway][!surface] {
	set:	surface=paved;
}

This is done so I can assume default values later in the sheet, without having to test explicitly for untagged ways for each test. If it works on the implementation of mapcss, it will come handy on complex stylesheets.
