Pat, Peter,

I suggest to spend a few minutes at the telecon to discuss this. The 
editors of Concepts should maybe take responsibility.

Note: I noticed there was no issue for this, so I created one [1].
Note 2: I noticed that the text of Issues 38 in the tracker had no link 
to the resolution; corrected that as well.
