We combined the drafts based on the suggestions from the Berlin meeting. 
There might be other ways to describe the solution. Based on the results 
of the discussion in Chicago, we can try to think about a series of 
drafts that might be easier to read because each draft would be focussed 
on a smaller subset

Let's discuss this on the list after the meeting since I will only 
attend remotely
