Good question. I'm not sure. OSM's data should at least include 1)
service roads (to decrease the distance between the POI and the
nearest road, which should decrease ambiguity), and 2) entrances (to
resolve ambiguity in the case of more than one very close roads).

On a related issue.... re: 2), in the case of multiple businesses
sharing a building (e.g. a typical AU shopping centre with entrances
on the outside of the building), is it advisable to place a POI node
*on* the building outline, rather than floating in the middle of the
building? This seems sensible to me, as this is equivalent to tagging
the location of the sign with the shop's name and/or the location of
the entrance to the shop. Another advantage is that if the building is
connected to the road grid, or a footway, etc., this may make it
easier to route directly to the POI.
