In OWL-DL it is so restricted. Emphasis on the DL. So, don't use  
owl:sameAs. Use your own propietary sameAs; it needn't even be  
symmetric. We are after all taking RDF here, not OWL-DL. And in the  
case under discussion (keeping Jeremy from losing thousands of dollars  
or much restful sleep), nobody outside the company is ever going to  
see the strange sameAs triples which protect his archaic but expensive  
code from the wild syntactic deviance in the new RDF.
