Thank you for the last round of comments.
Our 14 day process is almost complete and I wanted to send a copy of our paper so that BC colleagues in Nairobi will have a position to speak to.
 
I attach a version three factoring in the last round of comments / support. This includes all substantive contributions of content though not all of the style suggestions. Us rapporteurs should be free to retain that element!
 
For good order I also attach a clean version 3 and have entitled it "final" to facilitate any external communication in Nairobi.
