How to fix PDF-13
The XMP Version is not a known value
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
Version in the XMP is the version of the XMP schema: 1.0 for Factur-X and ZUGFeRD (1p0 and 2p0 occur in older files), or the XRechnung version (1.2 to 3.0) for the XRECHNUNG profile.
How to fix it
Set Version to 1.0 (or the XRechnung version for the XRECHNUNG profile).
