How to enable XML self-closing format for empty fields while rendering XML with Pkl ?
I would like to use the built-in XML renderer of Pkl but I cannot find a solution to change the XML output for the empty fields, is there even an existing way to enable self-closing format in the Pkl CLI? Is there a flag SelfCloseEmptyTags or smth that I can set true?

I know that the open/close format is basically the same, which is currently done by Pkl, but I would prefer to have the self-closing format. Thank you for the support !

The renderer currently doesn't support this; feel free to create an issue for this though.

Alternatively, we accept PR's too!
