pdf/A-2a is not pdf/ua-2. pdf/A-2a is for pdf 1.7 or less, so you would need pdf/ua-1 as accompanying accessibility standard and not ua-2 which is for pdf 2.0. But if context still maps everything to NonStruct it can't claim that the document is pdf/ua-1. The UA-standards clearly require that structures elements should be semantically appropriate. I don't own the pdf/A-2 standard so I don't know how it exactly defines the accessibility for the "a" in 2a, so it could be enough to simply enable tagging. -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
