Hi,

   I'm creating an ontology on the "cosmos" and I wanted to create sets for
Stars:  White Dwarf, Red Giant, ...
I can restrict the star type based on a temperature property, but don't know
how to say,

If property "temperature" LessThan 4000, then "WhiteDwarf".

I started with,

<Class ID="WhiteDwarf">
  <subClassOf  resource="#Star"/>
  <restrictedBy>
    <Restriction>
       <onProperty resource="#temperature"/>
  
         --      what would go here?

     </Restriction>
  </rescrictedBy>
</Class>

But need clarity on restricting the property to < 4000.

Thanks,
Larry
