text: How about not. I'm pretty sure it's already been established that 
  official zoning" and OSM landuse tagging are different things. I don't feel like the need to rehash it either. Especially with you. People see "retail" stores/a "retail" area on OSM, they should see retail landuse. A good example is slightly above here with what could technically be residential landuse due to housing above shops, but is rightly IMO tagged as retail, because that's how OSM prefers it. People can look at official city maps to findout officially city landuse. In most places, doing a 1/1 conversation would be extremely worthless though and not help map consumers. Again, I'm not relitigating it. Take it up with the tagging mailing list if you don't think retail landuse should be used for shops.
