[Tagging] building=yes on nodes?

[Lukas Sommer]

Hello.

The english wiki page key:building says that this key may not be used
on nodes. However, most (but not all) of the english wiki pages for
the individual values (like building=apartments) allow the usage on
nodes.

I’m not sure if it is useful to have a different policy for different
values here. Wouldn’t it be more useful to have to have the same rules
for _all_ values of the key “building=*”?

PS: By the way: In the german wiki, most pages for the individual
values do _not_ allow usage on nodes.
