the phrase, "proceeds with the server sending the version it  
supports", is to mean that the specification's notion of "accepts"  
permits a broker to reply with a Connection.Start with the major and  
minor server properties set to reflect the version it supports, but  
with no required relation to the requested version, and that standard  
practice is to permit just values less than that requested? is the  
behavior specific to rabbitmq? universal to all r8.0 brokers?
