I like versioning in all things, but sadly we never discussed it in Anntoea.

I like this solution.  It seems to generalize to all sorts of resources
and it's easy to add to the model.

This does have the side-effect that annnotations of version n are not
naturally retrieved with version n+1.  That's true, of course, for all
annotated resources that are versioned if the version identifier is
part of the URI.

We did not consider this use case either.

We did talk about this use case quite extensively and did plan to
permit multiple context triples exactly as you suggest.
