CII D16B XML for ERP and EDI pipelines

Raw UN/CEFACT D16B XML with profile-aware validation and the current EN 16931 rule set behind it.

CII (UN/CEFACT Cross Industry Invoice, D16B) is the other EN 16931 syntax, alongside UBL. ZUGFeRD, Factur-X and the CII variant of XRechnung all use it.

Use the API when an ERP or EDI pipeline already speaks CII and you need EN 16931 validation or a conversion to UBL.

Where it applies

• Germany · ZUGFeRD / XRechnung CII. CII syntax accepted for hybrid and B2G
• France · Factur-X. CII is the embedded XML of Factur-X
• EU · EN 16931. Semantic model independent of UBL vs CII syntax
