Keep the initial list short.  Our goal isn't to anticipate all future  
participants, rather to provide a mechanism that will permit new (or  
quite mature) vocabularies to be added when needed.

Is there a practical limit to the number of vocabularies we will be  
able to support?  There may ultimately be dozens or hundreds (or more)  
distinct dialects.
