COMMENT:
----------------------------------------------------------------------

Hi,

Thanks for the this document.   Just a couple of minor comments.

It looked like the equation in section 2 was mucked up in the text version of
the doc.  Presumably this will get fixed during the editing process:

I.e.,
              __ 52                       fc
   version = \         present(fc) ⋅ 2
             /__ fc = 0

   Quantitatively, the expert could for instance steer the allocation to
   not allocate more than 10 % of the remaining set per year.

Rather than setting this is a limit, I would suggest that it is better to set
this as a target.  E.g., if it turns out that there is a good justification for
an extension, it would be a shame if it had to be delayed by a year merely to
fit into a somewhat arbitrary rate limiting scheme.

Besides, if you end up with 53 different optional extensions, then I suspect
that the bigger problem will be that there are too many variants of what is
supported by different implementations which will reduce interop, and you'll
probably want to end up with batches of extensions that are expected to be
supported together, i.e., some sort of hybrid between completely independent
extensions and a strict linear version scheme.
