Hi Hans (and Steffen),
I get mixed profiles with the following source:
\setupbackend[format=ua2] \starttext a \stoptext
The latest version of VeraPDF (https://software.verapdf.org/) complains of both PDF-2 UA-2 detected and PDF-1.7 A-3a.
In fact, only VeraPDF only validates PDF-1.7 (and results are a mess).
You can choose which standard you want to validate, on the command line with e.g. verapdf -f ua2 test-utf8.pdf (It won't validate as your document doesn't contain tagging).
I must admit I don’t know what may be causing the inclusion of the A-3a profile (marking).
No idea either, that is a context question. But PDF/A-3 is wrong together with PDF 2.0/UA-2 you need pdf/A-4. -- Ulrike Fischer http://www.troubleshooting-tex.de/
