Hi Norman

Why not the other way round? I would expect the geo: namespace to define 
very generic properties, independent of any specific use and any 
coordinates system.
Use in vcard is a specific one, so one would expect

 vcard:latitude   rdfs:subPropertyOf     geo:lat
> and nothing more.
With a geo: namespace more generic that is is now, that is, with no 
reference to wgs84, that is e.g. http://www.w3.org/2003/01/geo/ or  
http://www.w3.org/2003/01/geo/pos# ... whatever.
