This doesn't solve the common case of the shared campus or location
having a shared name, as in the French example I've linked to. A common
case in my experience; I have a named campus in my hometown that houses
a university, a college, and a research institute — each a distinct
organisation. The campus name is used in signage.

The association of school with campus can be deduced from the amenity
point/way lying inside the landuse area. This is the same as
amenity=place_of_worship inside a landuse=religuous.

I think the school amenity may also be linked to its grounds via a
relation, but that would go beyond the scope of this proposal.

Overlapping amenity areas also seem to go against the grain of most OSM
tagging solutions.

In these cases the current situation remains: using a node (or a way for
part of a building) for the amenity. The landuse for such a place might
eventually be one of those proposed in the landuse=civic proposal. I
think this is mostly an edge case though.
