VAT breakdown group 1 of the document states no readable VAT category rate (BT-119): the element is missing, empty, or not a plain decimal number. Each VAT breakdown (BG-23) shall have one, with a single exception: category O ("Not subject to VAT"), which has no rate at all — a different statement from a rate of zero.
BR-48State the VAT rate (BT-119) on every VAT breakdown group of the document, zero included. The only group without one is category O, not subject to VAT.
