Hi
PDF/A files generated using ConTeXt fail validation with veraPDF, and
the reason seems to be that the dc:description metadata is defined with
the wrong type in the embedded XMP extension schema.

I can reproduce the problem using TeX Live 2021 (MkIV 2021.03.05). The
definition seems to be controlled by this code.
https://source.contextgarden.net/tex/context/base/mkiv/lpdf-pua.xml?search=rdf#l81
so "dc:description" is not permitted? it is mentioned in
https://www.dublincore.org/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/elements/1.1/description
(btw it never failed before)
