            Bug ID: 139736
           Summary: Images and frames in header violate PDF/UA
           Product: LibreOffice

          Hardware: All
                OS: All

          Severity: normal

Example odt from which the pdf is created

Description:
The new PDF/UA export function allows to export PDFs which comply with the
PDF/UA standard.
When images or frames are added to the header the pdf export creates pdfs which
violate PDF/UA. PAC3 says that these images/paths/texts are objects which are
not tagged.
The elements in the header should be tagged as artifact (as far as I know). At
the moment VoiceOver (default macOS screenreader) with Adobe Acrobat ignores
the elements in the header (as it should be), but to comply the standard they
should be tagged as artifacts.

Tested:
Tested on 7.0.3.1 and dialy master build which contains the fix from bug
#139643.

Steps to reproduce:
1. Open new Writer document and add a title in the preferences.
2. Add Header and add an image, also set alternate Text for that image.
3. Add a frame with an example text to the header.
3. "Export as PDF..." with "Universal Accessibillity (PDF/UA)" enabled.
4. Test document with PAC3: Image/Text/Path object not tagged.
5. Accessibility check with Adobe Acrobat shows also issues with the image and
frame object in header.

Reproducible: Always, all OSs

Attachments:
- Example odt
- Created pdf 
- Screenshot of issues in pac3 (I do not know why the issues itselfs are in
german but in english they are: Image object not tagged, Text object not
tagged, Path object not tagged)
