How can we get hyperlinks to pass the PDF/A-3a validation

pdf-a

The following example is from a reply to Solutions for creating a PDF/A-3a

Hyperlinks were disabled with \hypersetup{draft} to pass the PDF/A-3a validation (in veraPDF=. Without this line, the validation fails with this message:

Specification: ISO 19005-3:2012, Clause: 6.3.2, Test number: 1

Except for annotation dictionaries whose Subtype value is Popup, all
annotation dictionaries shall contain the F key.

Any suggestions on how get links that pass the validation?

\RequirePackage{pdfmanagement-testphase}
\DeclareDocumentMetadata{
    pdfversion=1.7,
}
\begin{filecontents}{\jobname.bib}
@book{mybook,
    author={Some Author},
    date={2021},
    title={Some title},

\end{filecontents}
\documentclass{article}
\usepackage[tagpdf]{axessibility}

(updated october 2023 to the new state of the project)

  • pdfx is not compatible with the pdfmanagement.
  • hyperxmp is not compatible either. xmp-metadata are provided by the pdfmanagement.
  • The pdfmanagement allows to set a pdfstandard, but in the current version A-3a is not supported.
  • I have now added a first, preliminary support for A-3a, so with the next pdfmanagement version (0.95i) the document below will pass validation.
  • The axessibility package does not create a tagged pdf. It only tags a bit the math. All the rest is tagged as artifact. From the point of accessibility this is quite useless. Also the package is no longer compatible with a current version of tagpdf.
  • you can try to activate more tagging as shown in the document with the testphase option and testphase=phase-II or \testphase=phase-III but be aware that in a real document lots of things can fail.
\DocumentMetadata{pdfstandard=A-3a,
    pdfversion=1.7,
    testphase=phase-II, %activates paratagging
    %debug={para=show,uncompress}
}
\begin{filecontents}{\jobname.bib}
@book{mybook,
