Sure, my proposal to close ISSUE-16, as written, doesn't directly
address Alan's concerns.  I suppose that one could somehow link these
concerns to some wording in
http://lists.w3.org/Archives/Public/public-owl-wg/2007Oct/0398.html but
I didn't see a direct link.

At this point I think that the WG should be looking for minimal
solutions that can support future work in various areas.  My view is
that extending the syntax of annotations (to allow annotations on
annotations) is such a minimal solution, that would then allow tool
vendors to investigate the space of solutions, which could then coalesce
into a common solution.  

In essence, this is what the OWL 1.1 annotations did - providing a
syntactic mechanism for adding annotations to axioms, in the absence of
any agreement on any meaning for such annotations that could be
compatible with performance reasoners for OWL.  The metalevel work
reported in
http://www.comlab.ox.ac.uk/people/boris.motik/pubs/dhmgh08-metalevel-information.pdf
goes further, and may indeed be the way forward, but the jury is still
out on this, I think.

I would also be satisfied if no change was made to annotations, by the
way.
