I didn't see a clear consensus on what to do for this. Since
the change calls for adding additional explanation in an area
where (it seems from the list) we're not clear on what terms
to use in such additional text, I think in the absence of
further discussion the best thing might be to close this one.

If no-one objects, I'll ask Eliot to close this on July 11th.
