`validate_xml`Validate an XML document with xmlvalid: well-formedness, an XSD, DTD or RelaxNG schema, and for e-invoices the Schematron business rules of EN 16931, Peppol BIS, XRechnung, Factur-X and national formats. Pass the document as `xml` (its text) or `url` (a public http(s) address), and a `schema`: a catalog slug from search_schemas, a saved schema ("@orders-v3"), or "auto" to use the e-invoice profile the document names. Without a schema only well-formedness is checked. Returns valid, errors and warnings with line, column, message, rule and a help_url explaining each. Counts as one API validation of the account's monthly quota.
