I have been wondering about this word "mandatory". Is it semantic 
matter, as in "you are not a compliant TAP service"? Or, by contrast, 
are you saying that if a publisher puts up a Synchronous service with 
valuable data behind it, then the IVOA should refuse to register it or 
connect tools and services to it?
