Validation rules

BR-DE-14

A VAT breakdown is missing its category rate (BT-119) — XRechnung requires cbc:Percent in every tax subtotal, including category O (where it is 0).

Rule: BR-DE-14 — official EN 16931 / XRechnung rule
Severity: error
Business term: BT-119
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

normbill writes the rate in every breakdown it generates — including Percent 0 for category O, which plain EN 16931 leaves optional but XRechnung mandates.

How to fix it

Add cbc:Percent to every cac:TaxSubtotal/cac:TaxCategory.
