[Tagging] Give Way and Stop in two-way street

[Noel David Torres Taño]

Hello all:

There are some streets which, being two-way, one way has a Stop or Give Way 
and the other has not. How to tag them?

My proposal is splitting the street in two highways with same name, same tags, 
etc, each one being one-way and exactly the same nodes, with one of them 
having an extra node for the Stop.

Maybe some extra relations for this?

Thanks

Noel
