Validation rules

BR-TMP-CVD-01

In a CVD invoice, the item classification scheme (BT-158) must come from the UNTDID 7143 code list.

Rule: BR-TMP-CVD-01 — official EN 16931 / XRechnung rule
Severity: error
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

Belongs to the 'XRechnung CVD' sibling CIUS (Clean Vehicle Directive) — a separate CustomizationID normbill never generates; reachable only for CVD XML submitted to /v1/invoices/validate.

How to fix it

Use a UNTDID 7143 scheme identifier on the item classification.
