-	Issue(6790): Should ''@scope'' use strong or weak scoping proximity?

-	[=Weak scoping proximity=] causes declarations of the same specificity
-	to be weighted by proximity to their scoping root
-	before falling back to source ordering,

-	The Working Group currently leans towards weak proximity,
