Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.
The Item classification identifier (BT-158) must have a Scheme identifier. The message starts with "The", not "Each", and says "shall have a Scheme identifier". It ends with a period. The context is the item classification code on an invoice line or a credit note line. The published test checks that the listID attribute exists. It does not check a schemeID attribute, and it does not check the list value.
When an item classification identifier (BT-158) is sent, give that classification code a listID attribute.
Illustration of the condition in the official statement. Not an example published by the source.
Fails the stated condition. An item classification code has no listID attribute.
Passes the stated condition. That classification code has a listID attribute.
