What is the "unifying tag" you propose, and how would it work?

I'd love to see stop areas go away, or at least limited to instances 
where the link between stop position and platform can't be deduced from 
geometry.  Heck, in most cases, the stop position itself can be deduced 
from the platform and route geometry--assuming the platform is in the 
route relation, which isn't always the case.
