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.

https://github.com/veraPDF/veraPDF-library/issues/1224

I can reproduce the problem using TeX Live 2021 (MkIV 2021.03.05). The
definition seems to be controlled by this code.
