Hello everybody,
We are trying to embed ZUGFeRD XML into a PDF/A file to produce a valid ZUGFeRD
e-invoice. To validate the result, we use the Mustang Projekt CLI
(https://www.mustangproject.org/commandline/) using this command:
$ java -jar Mustang-CLI-2.16.2.jar --action validate --no-notice --source
Beleg_245210299_20241201_out.pdf
However, the PDF/A file seems to be invalid, since we receive this error
message:
<?xml version="1.0" encoding="UTF-8"?>
<validation filename="Beleg_245210299_20241201_out.pdf" datetime="2025-02-14

Can anybody point out how to “fix” the resource dictionary for the font using
PDFBox? Are there any examples? Attached is the resulting PDF/A file including
the ZUGFeRD XML which causes the error.
Thank you very much for your help!
