I started trying to work out use cases for backwards compatibility (old 
documents, new tools / old tools / new documents), and realized I don't 
have enough experience (or patience?) to propose anything definitive or 
thoroughly considered.  Still I feel that the success of this whole 
enterprise will very much hinge on getting the nuances of the 
compatibility decisions just right, so smart people: please think deeply 
about this!
