Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-17.
On a document-level allowance whose VAT category is "Intra-community supply", the allowance VAT rate (BT-96) must be 0. The official message spells that category with a hyphen. The published test checks that the percent, read as a decimal, equals 0 where the allowance category code is K. The context writes cbc:ID)='K' with no space before the equals sign.
Set the allowance VAT rate (BT-96) to 0 on each allowance coded K.
Illustration of the condition in the official statement. Not an example published by the source.
Fails the stated condition. An allowance VAT category code is K and the allowance VAT rate is 19.
