How to fix PDF-07
The invoice XML is not listed in the catalog /AF array
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
PDF/A-3 associates an embedded file with the document through the /AF (associated files) array of the document catalog. ZUGFeRD and Factur-X require the invoice XML to be associated this way.
How to fix it
Add a reference to the file specification of the invoice XML to the /AF array of the catalog.
