# Factur-X / ZUGFeRD EXTENDED

Source: https://xmlvalid.com/schemas/factur-x-extended

> The Factur-X and ZUGFeRD profile with more data than EN 16931, for industries that need it.

EXTENDED adds fields that EN 16931 leaves out, such as more party roles, delivery details per line and sub-lines. It is a superset of the EN 16931 profile.
Two layers are checked: the profile schema, then the profile's Schematron rules with their code lists.

## Notes

- In the validator you can drop the PDF itself: its XML attachment is opened and the profile picked from its specification identifier. So do the API and the command-line client. Rules run only when the document matches the schema.
- The schemas, rules, code lists and example come from the akretion/factur-x library, which ships the official files unchanged.
