# UN/CEFACT Cross Industry Invoice D22B

Source: https://xmlvalid.com/schemas/cii-d22b

> The D22B release of the CII schema, the syntax the French e-invoicing reform names for CII invoices, with uncoupled code lists.

D22B is a later release of the UN/CEFACT Cross Industry Invoice than the D16B subset of EN 16931, with more elements; Factur-X 1.09 and the French reform (XP Z12-012) build on it. In the uncoupled version, code values are plain text, so the Schematron rules check them, not the schema.
An invoice that passes D16B passes D22B too; the reverse is not always so.

## Notes

- This entry checks the schema only. For the French rules, choose a French CII entry.
- The schema files are those FNFE-MPE publishes with its validation artefacts (the main schema and the three data type schemas it imports; the code list schemas are not used by the uncoupled version).
- The example is use case 13 of the FNFE-MPE examples for XP Z12-012 (Apache License 2.0).
