Description

I get with the files pdfa_article_v11.pdf and PDFExportDialog2.pdf of the "unclear" part of the Bavaria test suite. The cause is text like this in a PDF:

9D978E 6C6456 CECBC7 B5B1AA F3F2F1 E6E5E3 473D2C 857E73 DAD8D5 F3CFD2 DB6E7A 544A3A 605748 C2BEB8 E79EA6 D24A58

In a comment to PDFExportDialog2.pdf, pdflib tells "Unclear: hexadecimal string with whitespace characters (ambiguous in ISO 19005-1)" and "PDFlib opinion: whitespace in hex strings should be ignored". The PDF-Tools validator says it is a valid PDF. Solid Documents is unable to process the file.

msahyoun do you know if this has been clarified in PDF/A-2b or PDF/A-3b? It is valid in "ordinary" PDF files.
