[OSM-talk] Tag combinations: amenity and highway

[john whelan]

I wonder about lumping things together sometimes.  Locally we have gas
stations amenity=fuel that have a convenience store and a ABM or ATM in OSM
language.  I'm tempted to have three separate POIs in much the same way as
a bank with an ATM have two POIs together.

The problem with putting too much information on one POI is the rendering
systems have problems with more complex coding especially how do you
display it?  Even to distinguish between a bus_stop and a bus_stop with
shelter in a simple way with different icons doesn't seem to be
standardized.
