I've replaced the vcard box with some brief text saying we "recommend 
the vcard ontology".

Looking at the OWL I didn't see much in the way of axioms about 
v:Location. Possibly the relevant properties are open-domain. I 
sometimes use the non-standard (but not harmful) trick of declaring 
minCard(0) restrictions as a way to hint that a property might be used 
on a class without requiring it.[1]

Great, thanks for confirming.


[1] The question of how to say "property X is mandatory but if you want 
to express concept x here then please use property X for it" is a 
recurrent need in semweb modelling :)
