Thank you, Toke.

Denis, I believe that we are saying everything that needs to be said in
the paragraph above.  Please spell out exactly what you think is missing.

To be very clear: don't give me stylistic suggestions, say something like
"The draft needs to say that 2 + 2 SHOULD be equal to 4, and it doesn't."
