These are the EN 16931 business rules of this family, as published by CEN/TC 434 in the validation artefacts that accompany the standard. The wording here is the rule text itself, and it is never a paraphrase. The codes in parentheses are business terms (BT-) and business term groups (BG-), the semantic model's names for the fields a rule constrains, and the location given with each rule is where it is asserted in a UBL invoice.
