Why is there a difference between @rel/@rev and @resource/@about in this 
respect? After all, we could argue that we could put a full URI into the 
@rel/@rev value, too... In all cases the value of CURIE-s is that I do 
not have to type in a full, long, and possibly complicated URI... (which 
I have to do all the time in RDF/XML, and it is quite a pain...)
