Validation rules

BR-62

The seller electronic address (BT-34) has no scheme identifier.

Rule: BR-62 — official EN 16931 / XRechnung rule
Severity: error
Business term: BT-34 — Seller electronic address
Field in your JSON: invoice.seller.electronic_address
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

invoice.seller.electronic_address.scheme defaults to "EM" in the request schema, so generated endpoints always carry a scheme.

How to fix it

Set the schemeID attribute on the supplier cbc:EndpointID to an EAS code, e.g. EM for email.
