Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL

Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.

## Plain-language reading

The value added tax point date code must use a restriction of UNTDID 2005. The statement says MUST and ends with a period. The context is cac:InvoicePeriod/cbc:DescriptionCode. The test allows only 3, 35, and 432, and it rejects a value that contains a space. It does not call exists.

## What to change

Set the invoice period description code to 3, 35, or 432, with no space.

## Illustration

Illustration of the condition in the official statement. Not an example published by the source.

**Fails the stated condition.** The description code contains a space, or it is not 3, 35, or 432.

**Passes the stated condition.** The description code is 35, with no space.
