Note that the only mandatory field in an hCard is name; there is no 
requirement for any contact information to be included. It is there fore 
implicit that hCard can be used to mark up that fact that string of text 
identifies a person ("Fn") or organisation/ venue ("fn org"), and no 
more than that.

It certainly isn't a bad thing, and its the default behaviour in a 
number of cases.

Consider, for instance a geo microformat, wrapped in an hCard with jsut 
an "fn org", as a labelled waypoint - no contact info, but useful 
semantic information.
