Validate E-Invoice XML
validate_einvoice_xmlValidate e-invoice XML documents against schema and business rules to catch errors before dispatch. Returns detailed validation errors with severity and location.
Instructions
Validate an e-invoice XML document against the specified format's schema and schematron rules. Returns a list of errors with severity, XPath location, message, and rule ID. Runs KOSIT validator (XRechnung), Mustang (EN16931), XSD, or Schematron depending on format.
Use before dispatch to catch errors early without incurring network transmission costs. A valid=true response means the document passes all schema + business rule checks.
If the validation backend is not deployed for this workspace, returns an honest 'unavailable' response — never a fabricated valid=true. / Valida un documento XML de factura electronica contra el esquema y reglas schematron del formato especificado.
