That was my initial approach, but unfortunately there's no way to select 
an element whose sorted="" attribute does not contain a space-separated 
keyword that is an integer other than 1, which is what I'd like to match 
here. (We don't technically need the argument, since you _can_ match on 
the attribute having a "reversed" keyword, but it seems cleaner to do it 
all with a pseudo once you're doing any of it with a pseudo.)
