Mime type of embedded files is lost after converting to PDF/A-3B


it seems that the mime type of all embedded files is set to pdf after converting the pdf file to PDF/A-3B.
I would have expected that the mime type would not be changed because we are converting to PDF/A-3 here. This standard supports embedded files of any type.

Test PDF file with embedded files before converting to PDF/A-3B: Zugferd_2.pdf (1.0 MB)
Code: Code snippet for converting in Java.zip (537 Bytes)

Thanks a lot.

Best regards
