As Christian Quest explained on talk-fr just minutes ago, an address is 
all that and more: a building, a cadastral plot, an entrance, a piece of 
equipment inside... But foremost it is an identifier - being at a 
specific geographic position comes second to that.

Absent any information, tagging the plot is better than nothing. A 
building is better - and even better is the main entrance or an even 
finer scheme to separate entrance and postbox... But as Christian said, 
learning to walk precedes learning to run - having an address at all is 
the essential step.

Also, the address must be unique - it must not be present on more than 
one object, even if more than one POI exists at that address.
