This issue similarly affects building=dormitory. Many university 
dormitories I'm familiar with are physically just wings of a larger 
building complex, similar to how multiple schools can share the same 
building. The individual dormitories have names distinct from the 
overall building's name ("___ Hall"). But unlike amenity=school, there's 
no established non-building tag for dormitories; building=* does double 
duty as a point of interest tag. I've tried various approaches over the 
years, none of them satisfying:

* Multiple connected building=dormitory areas joined by a multipolygon 
relation that's also tagged as a building
   * Buildings within buildings.
   * Probably conflicts with the simple 3D building specification
   * Doesn't work when different dormitories occupy different floors, 
one atop another.

* Multiple connected building=dormitory areas within a 
landuse=residential area named after the overall building
   * Landuse areas within landuse areas.
   * The name belongs to the building, not the land around it.
   * Also doesn't work when different dormitories occupy different 
floors, one atop another.

* Multiple connected building:part=dormitory areas within a building area
   * Conflicts with the simple 3D building specification, because these 
"parts" are orthogonal to the actual structural building parts.
   * The dormitory names don't render, even though they're more 
important than the overall building name, because structural building 
parts normally don't have names.

* Multiple landuse=residential residential=dormitory areas within a 
building area
   * Surprises data consumers that expect landuse areas to contain 
buildings, not the other way around.

* Multiple amenity=dormitory areas or points within a building area
   * Inconsistent with the vast majority of dormitories; ideally, all 
would be tagged amenity=dormitory.
