What the validator checks
The validator analyses Factur-X PDFs and UBL or CII XML files. It checks for structured data, safe XML parsing, format detection, the XSD schema and available business rules. For a Factur-X PDF, it also checks PDF/A-3b compliance when that service is available.
This is an automated technical check: final acceptance depends on your Approved Platform requirements and business context.
