## 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.
