I think this is probably a good approach, but I'd refine it a little bit
and say that the "main" namespace should not so much dereference to the
"latest" ontology, as the "latest release".  There can (and probably
should) be alpha- and beta-test versions which are "later" but not (yet)
suitable replacements.

Make sense?    (I've never done this with ontologies -- there could be a
problem with it -- but i think it's right.)
