Right: we still need to capture the semantic requirements. I don’t think we need to change either of the quotes that you (Jeremy) brought out. My remark was purely about the description of the "R-PackagingOfMultipleTables” requirement which is phrased as a requirement for packaging rather than as a requirement for grouping tables so that annotations can be assigned to the group, which is what I think it really is.
