I can't see why you keep bringing up "tagging for routing software".
We need to model the world. We need to define the meaning of the tags
we use, *explicitly* (need I remind you of the path/footway/cycleway
debacle?). That's all James is saying. A *side effect* is that it is
able to be processed.

Knowing "what junctions are what" is not the same as knowing "which
junction a stop sign applies to". I don't see why you think this
shouldn't be defined explicitly... Please let us know your definition,
if you have one.

You also seem to be saying that "routing software" should work out
*for itself* which junction the stop sign applies to. I disagree - the
mapper on the ground should be able to enter this information in the
database.
