Etric, Thank you very much for this and continuing to work on it.

It may be that working in UNIX Operating System 
debugging for a few years has turned my brain 
peculiar, but I certainly find it fascinating 
browsing through the tags folks have been using. 
http://etricceline.de/osm/Europe/En/tags.htm

It is certainly turning into a very useful 
adjunct to the Map Features proposal process 
(sorry, Frederick, adjunct not replacement :-) 
).  The building= tag, stalled as a proposal, has 
developed a fairly finite coherent set of values 
just by being used. I've used 'palace' twice and 
notice that up to 38 other people have thought of exactly the same thing.

building=
yes (100873), residential (2027), detached 
(1876), apartments (1362), block (912), true 
(572), university (502), school (324), warehouse 
(317), hall (311), barn (268), building (210), 
commercial (208), farm (182), house (177), 
industrial (174), hospital (171), flats (156),

(125), public (112), train_station (109), semi 
(107), office (106), castle (98), supermarket 
(94), terrace (88), garage (83), tower (80), 
city_hall (70), stadium (69), station (67), hotel 
(57), museum (55), glasshouse (52), shop (49), 
place_of_worship (46), recreation (45), palace 
(40), hall_of_residence (39), bunker (37), 
factory (36), shed (36), wall (33), appartments 
(29), stables (27), prison (26), pavillion (26)

Also,

building:use=

Residential (14), flat (13), Hospital (11), sport
