Please see the attached document with all my comments to the authors.

Dear authors, thank you for your comprehensive and clear responses to my comments and for the improvements you made to the manuscript. I don't have anything to say or add (which is good!). I am particularly happy about this experience coming directly from finishing a revision of another paper which proved much tougher. Please, continue to manage the peer-review process this way; very well done! All my congratulations and best wishes for this publication (and maybe more!).
