Well, I just made ::* be a synonym for the generic case for now. And
generic rules never override rules for specific subparts. But that is
mainly just to make my implementation easier. I agree that ::* should
probably override things too.

Can you give an example? Like this:

way [highway]::centerline {bezier:yes;} 
way [highway]::highlight {bezier:yes;} 

way [highway]::* {bezier:no;}

'::' is just another specific subpart. I wrote that to make sure that no
one things that:

way [highway]:: 
overrides
way [highway]::centerline

because (in my implementation) it does not.

This is all open to discussion of course.
