+1, basically you would tag buildings with the building tag, and either the
building type or yes as value, while functions are tagged with different tags.
building=hospital doesn't say there is an active hospital, it only states there
is a hospital building.
On the other hand, functions like schools or hospitals typically extend beyond
a single building (eg there might be a yard, a garden/lawn, a parking etc), so
the "normal" situation would be to map an area for this function and within the
buildings with their building types (or yes).
If you encounter a building that is (entirely or at least for one entire floor)
occupied by something that doesn't extend beyond the building area it might
still be better not to mix these 2 entities on the same object (but I admit it
is frequently done). If you want to distinguish between these two you can for
example map the building as area and create a multipolygon relation with just
one outer member (the building) for the function. Alternatively you would have
to create an overlapping way which is less elegant and harder to edit, or you
just use a node inside, what will loose information (about the extent).
