Step back a little perhaps.
I don't think we can (or should) predict that version X could or should
be a valid version Y instance? We can't see into the future and requiring
backwards compatibility will hold back ODF IMHO.

Perhaps the question should be, what do we expect a processor to do
when it meets a verison
a) Earlier
b) Later
than the one it expects.

sections 3.8 and 3.9 may be of help.
