[Ally]: cannot see title with A-4F standard

[teepeemm]

Ally reports that the following

\DocumentMetadata{
  lang=en,
  tagging=on,
  pdfstandard={ua-2,a-4f},
  tagging-setup={math/setup={mathml-AF,mathml-SE}}
}
\documentclass{article}
\title{Title}
\begin{document}
\maketitle
content
\end{document}

"does not have a title". VeraPDF reports that it is compliant with UA-2 and A-4F.

AllyA4Title.pdf

Ally is looking for DocInfo, and that's explicitly forbidden with A-4f so is suppressed. So the result is not really a surprise.
