Dear Karl

I agree with Karl about this:

While I agree we should not assume a default for missing bounds, I think it
would be good to recommend that bounds should be included. At present we do
not do this. If we made it a recommendation (in section 5.1), the CF_checker
would give a warning if there were no bounds.

Cheers
