What I'm doing right now is tag the roads inside this zone with maxspeed=50 and source:maxspeed=city_limit.
This doesn't fit entirely, as it doesn't only influence maxspeed. Maybe adding a tag city_limit=yes would be more appropriate? Besides there is a conflict when inside those city limits there is a zone30. I'm tagging those with maxspeed=30 and source:maxspeed=zone30. The zone30 also has some extra consequences, besides maxspeed though. Would it be more correct to use zone30=yes? We also have zone50 and zone70. I have been tagging the location of city_limit signs for several years now, but since we didn't have a tag for it, I simply used note=city limit or bebouwde kom (nl). I hope a proper way of tagging them will come from this discussion.
