Description: LibreOffice exports PDF/A-1a when asked to export to PDF/A-1b. This can be tested with the verapdf tool. It must be an explicit choice in the code since the output PDF claims PDF/A-1a compliance, and indeed also is compliant to the standard. Important: This is not about accessibility (PDF/UA) but archive PDFs (PDF/A). If the export is PDF/A-1a, I'd recommend to write that in the dialog. Perhaps the export is not always PDF/A-1a but sometimes only the less structured PDF/A-1b (as the export dialog claims). Then please document when this happens. At least document that LibreOffice sometimes outputs PDF/A-1a compliant documents, in the export dialog, or in the docs. Steps to Reproduce: 1. Export PDF/A-1b compliant PDF Actual Results: Obtain (undocumented) PDF/A-1a compliant PDF Expected Results: See the difference Reproducible: Always User Profile Reset: No Additional Info: The software should indicate what is possible to do
Help page, that should be updated: https://help.libreoffice.org/7.4/en-US/text/shared/01/ref_pdf_export_general.html?System=WIN&DbPAR=WRITER&HID=filter/ui/pdfgeneralpage/PdfGeneralPage#bm_id1033968 Basic information about difference between PDF/A-1a and PDF/A-1b: https://en.wikipedia.org/wiki/PDF/A
The bug description indicates that exporting to PDF/A-1b produces PDF/A-1a. This is a bug in PDF export. There is no point in producing end user documentation of a bug that should be fixed. Resetting component.
