Hi Russ and Gregor, thanks for your feedback,
I think that I made most of the points I was thinking about and hope that some of them related to Simple English and jargon can be useful in the future. I also understand your point of view. One final comment I would like to make is that the format is used in other contexts, such as Apt (using "paragraph" in https://wiki.debian.org/DebianRepository/Format), DEP-11 (using "block" in https://wiki.debian.org/DEP-11), and probably other files generated for the Debian archive. I recommend to keep producers and consumers of these files in the loop before changing Chapter 5. As for on which word to standardise on, I trust the Policy Editors to make a good choice, even if it is not my favourite. Have a nice week-end, -- Charles
