[Tagging] Tagging buildings that people work in

[ET Commands]

In the course of my mapping I sometimes encounter buildings that I know 
people work in, but I don't know what kind of business is being 
conducted in the building.  These buildings could contain offices, or 
medical facilities, or factories, or warehouses, or retail, or just 
about anything else, other than storage buildings or abandoned buildings 
or something like that, where people are not normally present.  (Of 
course this is somewhat subjective, I realize.)  To distinguish these 
buildings from the ones that are tagged with "building=yes" I like to 
use a different tag.  I have been using "building=occupied" for lack of 
a better tag.  This tag, of course, is meant to be temporary until 
someone determines the proper nature of the use of the building.  In the 
meantime, this helps to distinguish "occupied" buildings on maps from 
generic ones.  What do you think?
