Field notes
The validator accepts several invoice representations, including Factur-X PDF, CII, UBL, and CDAR status messages, then separates container, schema, profile, European, and French-rule checks. Its example deliberately alters an official XP Z12-012 invoice and reports eight blocking failures. The page also exposes rule identifiers and correction guidance, including the required nine-digit seller SIREN format.
