Regarding having an explicit version field: I have thought about this 
more and I am happy with the text in draft 02 as it stands, as it leaves 
it free for future versions to define the reserved fields in more detail 
providing at least 1 bit is set to 1. I certainly wouldn't see the point 
in making the whole set of reserved bits into a version number as this 
could limit flexibility in the future.
