            Bug ID: 140958
           Summary: PDF/A-3b Exported From LibreOffice Writer is Showing
                    as Adobe PDF Version 1.6, Instead of 1.7
           Product: LibreOffice
           Version: 7.0.4.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When exporting as a PDF file (PDF/A-3b) from LibreOffice Writer and looking at
the file metadata using ExifTool, the PDF file is showing the Adobe PDF version
as 1.6, instead of 1.7.

According to the below link, PDF/A-3 is supposed to be based on Adobe PDF
version 1.7.

https://www.loc.gov/preservation/digital/formats/fdd/fdd000318.shtml

"PDF/A-3 is a constrained form of Adobe PDF version 1.7"

And also here.

https://www.loc.gov/preservation/digital/formats/fdd/fdd000318.shtml

"PDF/A-1, the first PDF/A standard [ISO 19005-1:2005], was based on PDF version
1.4 (see PDF-1-4) and published in 2005.

PDF/A-2 as defined in ISO 19005-2:2011, extended the capabilities of PDF/A-1
and is based on PDF version 1.7 (as defined in ISO 32000-1, see PDF-1-7). One
new capability was to allow the embedding of PDF/A-compliant attachments.

PDF/A-3 added a single and highly significant feature to its predecessor
(PDF/A-2), to permit the embedding of a file or files in any format. The intent
expressed by many proponents is that the embedded files not be considered part
of the archival payload. However, use cases are emerging where the embedded
files would likely warrant preservation by archival institutions."




Steps to Reproduce:
1. Open a new LibreOffice Writer document.

2. Go to File > Export As > Export as PDF.

3. Select the option for "Archive (PDF/A, ISO 19005)" and PDF/A Version as
"PDF/A-3b".

4. Click the Export button.

5. View the file metadata using ExifTool, which shows "PDFVersion: 1.6".


Actual Results:
The PDF file metadata from ExifTool shows the following:
