[xsl] Convert JSON to XML?

["dvint@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I know (and have been using) the xlst json-to-xml() function for this 
purpose, but it is a pretty basic result. I happened to try the JSON to 
XML funtion in oXygen and got what I'd say is a much better result where 
I had some unique elemeent names instead of everything being a map or a 
string element.

I was poking around to try and find a tool/library I could use in my 
conversion path and everything I'm finding is an online tool or has a 
price. Currently I'm developing a conversion pipeline and can leverage 
oXygen for this, but I need something I can build into a tool and load 
into a Docker image for the production implementation.

Anyone have a suggestion?
