There are “four way”/“all way” stops in my area where traffic on the primary road is required to stop. I map those by putting the highway=stop on the junction node. For those where not all the ways are required to stop, I put the highway=stop on the “limit line”. My reading of the wiki a while back implied that was all that was needed. More recently, based on mail list discussions, I have been adding direction=forward/backward on those too.

Not sure why a relation is needed for these as it is pretty simply to tag and, I assume, for a data consumer to use the current tagging.
