How to fix PEPPOL-EN16931-CL001
Mime code must be according to subset of IANA code list.
What this rule checks
Peppol restricts attachment MIME types to a specific subset of IANA media types (e.g. application/pdf, image/png, image/jpeg, text/csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet). This is stricter than the base EN16931 rules which do not constrain MIME codes.
How to fix it
Set cbc:EmbeddedDocumentBinaryObject/@mimeCode to one of the Peppol-allowed values such as 'application/pdf', 'image/png', 'image/jpeg', 'text/csv', or 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'.
