How to fix PDF-11
A ZUGFeRD / Factur-X property is missing from the XMP
A check of the PDF of a ZUGFeRD or Factur-X invoice, not of its XML. It runs when you upload a PDF; the embedded XML then gets the XSD and EN 16931 checks (XRechnung: also the KoSIT rules). Check your PDF with the ZUGFeRD validator or the Factur-X validator. What the PDF check covers.
What this rule checks
The XMP must have the Factur-X (urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#) or ZUGFeRD properties DocumentType, DocumentFileName, Version and ConformanceLevel. Receivers read the profile and the file name from them.
How to fix it
Add the missing property to the rdf:Description of the Factur-X namespace in the XMP.
