[OSM-talk] building entrances

My primary request was for a surface building with an outline (tagged as
'building=yes/hospital/whatever') and to have nodes within that outline with
'entrance=whatever' within the perimeter. No explicit relationship is
required in this case. I have tagged some entrances in the hospital here,
but of course they don't render yet:

I think underground stations are a special case in that they don't have an
obvious perimeter. Other stations are all muddled in with shopping centres
(Birmingham New Street for example). For these cases with a clear boundary
on the surface then relationships would certainly be useful and bind them
together. I would be interested in seeing how to model some London stations
in the near future this way.

We should probably include platforms as well (I was at a railway station
last week with 4 platforms, with three different 'entrances' each of which
served a subset of the platforms by going up and down lots of steps). I
think the 'station' itself should also be included as a feature, either as a
point or an area as appropriate, together with a number of entrance
features, platform features and linking walkways/steps/etc to join them up.
