Hi Alvaro, Thanks for the comments. I've discussed with the Chairs and Authors, and we will keep the document on the telechat for today. The Chairs and Authors think it is possible to change the language so the document can stand on its own. They believe the overall change is small (they already are scrubbing a version).
