Exactly what does broader/narrower mean?

Hi all,

A quick question.

In Wikipedia, there are often category hierarchies like this:

     Germany
       |
       +-- German politicians

Can this be translated to SKOS? If Germany and German politicians are  
skos:Concepts, then is there a skos:broader relationship between  
them? I'm a bit concerned that one isn't really a sub-topic of the  
other.

To phrase the question differently: Is there a clear test to decide  
if A skos:broader B? For RDFS class hierarchies it's simple: A  
rdfs:subClassOf B iff all instances of A are also instances of B.  
What would be the equivalent rule for SKOS?

Cheers,
Richard
