Vera PDF validation fails with metadata tags

Vera PDF validation is failing when using metadata tags with en error:

If a document information dictionary does appear at a document, then all of its entries that have analogous properties in predefined XMP schemas, shall also be embedded in the file in XMP form with equivalent values.

Specification: ISO 19005-1:2005, Clause: 6.7.3, Test number: 1

Vera PDF can fix this, but it would be good to have the correct format directly with img2pdf. The legacy tags are as at the moment:

<< /Author (--Author Name--) /CreationDate (D:20231016123139Z) /Creator (--Document Creator--) /ModDate (D:20231016123139Z) /Producer (img2pdf 0.4.4) >>

Current img2pdf generated XMP:

The validated XMP code generated by Vera PDF (notice for Creator we use xmp:CreatorTool and for Author pdfaid and dc:creator as there is no xmp:Author):
