How about simply creating a relation with those two nodes? You have an intersection of two (or more) roads and when you come to that intersection from one particular road (in one particular direction) you have a stop. Then you add a node on that way before the intersection, then create a relation (let's say of type=stop, or any more self-explanatory value) where you have the stop node with role "stop_from" and the intersection with role "stop_at". Such a scheme can be easily interpreted as: when you pass over a node highway=stop that is a member of a relation type=stop with role stop_from, then you must stop at the node of that relation that has the role stop_to. You might eventually add the way to the relation to avoid ambiguity in complex case, the way would have a role like "stop_along" and be interpreted to stop at the stop_at node only if travelling along that way.
