BR-CL-11

The scheme of a legal registration identifier (BT-30/BT-47 schemeID) is not part of the ISO/IEC 6523 ICD list.

Severity
error
Detected by
tier 3 — KoSIT validator (authoritative)
Reachability
Not expressible through the normbill invoice model — documented for completeness

The serializer emits legal registration identifiers (BT-30/BT-47 from legal_registration_id) without a schemeID attribute, so the ICD membership check can never fire on generated documents. Fatal in the primary CIUS scenario (only the Extension scenario downgrades it).

How to fix it

Use an ISO 6523 ICD value as the schemeID on cac:PartyLegalEntity/cbc:CompanyID, or drop the attribute.

BR-CL-11 auf Deutsch — was bedeutet der Fehler?

Das Schemakennzeichen einer Registerkennung (BT-30/BT-47, schemeID an cac:PartyLegalEntity/cbc:CompanyID) stammt nicht aus der ISO/IEC-6523-ICD-Liste. Das normbill-Datenmodell kennt keine Registerkennungen; KoSIT meldet die Regel nur als Information, die API filtert sie aus dem Report.

So beheben Sie den Fehler

Verwenden Sie einen ICD-Code als schemeID — oder entfernen Sie das Attribut.

Every 422 from the API lists the rule id, the path in your request JSON, a plain-language message and a suggested fix — see the docs overview for the report format.
