[NTG-context] mixed profiles in validation

[NTG-context] mixed profiles in validation

[Pablo Rodriguez via ntg-context]

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).

I must admit I don’t know what may be causing the inclusion of the A-3a
profile (marking).

Any ideas about what may be going wrong here?

Many thanks for your help,

Pablo

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).

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.
