[OSM-talk] "Campus", medical center, commercial?

[David Carmean]

Not finding definitive info on these questions in the wiki or mail archives, at least 
so far.  I have questions about how to draw two types of "campuses" or "sites".  The 
first example is a medical center, which may have one or more primary Hospital buildings 
and a number of smaller office buildings and facilities.   The other would be a 
large company campus (think Cisco, IBM, etc.)

Would these both best be done with an outer "landuse=commercial" area?
