Building 38446590 is shown in the centre of this map:

There are several pieces of information which might be rendered on the map,
or included in name searches:

   - The building is called 116, Pall Mall; it has no name apart from that.
     Obviously it can be tagged with addr:housenumber=116, addr:street=Pall Mall.

   - The building is the home of the Institute of Directors and it would be
     good to show that on the map.  Previously this was done with 'name'.
     But that seems wrong, since this is not the name of the building.

   - The IoD is not even the owner of the building.  It is owned by the
     Regency Crown Estate, and the IoD is just the most important tenant.

   - It was formerly used by the United Service Club, a servicemen's club.

   - There is an official website for the building and also one for its
     main tenant the IoD, plus a Wikipedia page for the IoD.

The trouble is that tags such as 'name', 'url', 'website' and 'wikipedia' are
too general.  They don't make a distinction between the building, its owner
and its tenants.  So far I have tagged owner=Regency Crown Estate,
user=Institute of Directors, but neither of these is rendered on the Mapnik
slippy map, so it's very tempting just to resort to 'name'.

Is there a convention for disentangling these things?
