PDF/UA XMP metadata missing so far

[viktoriasee]

Steps to reproduce

Compile a minimal file like minimal-pdftex.tex from this repository and run it through PAC3. The validator will give an error "Metadata->missing PDF/UA tag". Indeed when you watch in Acrobat->file properties->metadata you see it's not there.

Expected behaviour

A specific metadata is mandatory for PDF/UA according to ISO 14289‑1.

Comment

Scott from hxperxmp is working on implementing this in his package. So I suggest we don't waste time here and wait for it to complete. We can then add something like \Requirepackage{hyperxmp}

Seems like this metadata is needed for compliance with the accessible PDF standard.

I agree that it's better to wait for the hyperxmp package for a fix. Proposing to park this in the backlog and revisit it later.

hyperxmp is fixed now! I will update the minimal-pdftex.tex soon. However I do not recommend claiming a valid UA document now since the tagging problem is not solved.
