Hans, with the following source, veraPDF-1.29.11 complains about a non-standard tag named /documentpart: \setuptagging[state=start] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, level=0] \starttext whatever \pdfbackendactualtext{abc}{hoh} \stoptext The problematic object reads: 4 0 obj << /K 28 0 R /ParentTree 5 0 R /RoleMap << /break /NonStruct /document /Document /documentpart /DocumentFragment /navigationpage /NonStruct >> /Type /StructTreeRoot >> endobj If I replace (according to https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008....) /documentpart with /Part, validation in veraPDF is perfectly fine. BTW, /DocumentFragment seems not to be included in PDF-1.7 (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008....). According to https://github.com/veraPDF/veraPDF-model/blob/4c8e855b68546547971121281ff2ab..., /DocumentFragment seems to be only available in PDF-2.0. Providing a patch for strc-tag.lmt would be easy, but this would affect to ua-2 (which may use /DocumentFragment). Many thanks for your help, Pablo

Hi Steffen, I’m afraid that the some delay in new versions because of the release of TeX Live 2025 has been one of the few recent messages to the list from Hans. Not that anyone told me anything, but I guess he must be busy with other things (or he is just relaxing). I’m also interested in other things related to ConTeXt (and parallel texts), but there was no reply. So we will have to wait until Hans might have more time “to deal with the list”. Sorry, but this is the best news we seem to have. Cheers, Pablo

you can forget this thread in favour of “Alternate text for images?”. I was ignorant when I started the thread that there was: \enabledirectives [backend.usetags=crap] This was the way to avoid the use of the right tagging for PDF/UA-1. I hope it is clearer now, Pablo
