## Official statement

> The Seller electronic address (BT-34) shall have a Scheme identifier.

Source: https://docs.peppol.eu/poacc/billing/3.0/rules/ubl-tc434/BR-62/

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 Seller electronic address (BT-34) 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 seller party endpoint id. The published test checks that the schemeID attribute exists. It does not check the scheme value.

## What to change

When a seller electronic address (BT-34) is sent, give that endpoint id a scheme identifier.

## Illustration

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

**Fails the stated condition.** The seller endpoint id has no schemeID attribute.

**Passes the stated condition.** That endpoint id has a schemeID attribute.

## Published context and test
