Hello List,

I am looking for a way to add custom PDF properties to the document.

From the docs, I can see how to add standard properties (a.k.a headers)
like Title, Author, Subtitle and Keywords -
https://wiki.contextgarden.net/Interaction#PDF_Headers

But I would like to add my own custom Name-Value properties (similar to
what ConTeXt, by default, adds like `ConTeXt.Url=www.pragma-ade.com` when I
open the document in Adobe Reader).

Thank you for the help,

best regards,
