PD CEN/TS 16931-3-3:2026

This CEN Technical Specification (TS) contains the mapping between the semantic data model of an electronic invoice (EN 16931-1) and the UN/CEFACT XML Industry Invoice syntax. For each element in the semantic model (including sub-elements or supplementary components such as Code List identifiers) it is defined which element in the syntax is to be used to contain its information contents. Any mismatches between semantics, format, cardinality or structure are indicated. Any rules to be followed when using the specific syntax are stated informally in this TS. If later versions of the UN/CEFACT XML Industry Invoice support the semantics more accurately, this is indicated. For earlier versions (from D16B onwards) also a solution is presented.
