Steps to reproduce the problem:

\DocumentMetadata{
  lang        = de,
  pdfversion  = 2.0,
  pdfstandard = ua-2,
  pdfstandard = a-4f, %or a-4
  testphase   = 
   {phase-III,
    title,
    table,
    math,
    firstaid}  
}

\documentclass{article}

\title{test title}
\author{test author}

\begin{document}
\section{test section}
test text in section


\end{document}

Expected behavior:

when removing the documentmetadata from pdf tagging project
see https://latex3.github.io/tagging-project/documentation/prototype-usage-instructions.html
more meta data is shown in texworks pdf but not

• title
• author

\documentclass{article}

\title{test title}
\author{test author}

\begin{document}
\section{test section}
test text in section

\end{document}

for meta data shown partly after removal of documentmetadata command:
this is possibly because the \DocumentMetadata set, forces pdf version 2.0 which seems to include metadata in a different way...?

[u-fischer]

In PDF 2.0 the /Info dictionary in the trailer of the PDF is deprecated. Metadata should be added as XMP-metadata (and there are added in the example).
When you use a standard like A-4 or UA-2 deprecated features are not allowed and so the LaTeX-code suppresses the /Info dictionary and only adds XMP-metadata.

thanks @u-fischer

addition: the pdf produced with code shown in #1063 (comment)
fully passes pdf validation on https://dev.verapdf-rest.duallab.com/
