BPL, DTL and Rulesets in JSON and/or YAML

Sometimes when working with large rulesets, DTL, and BPL, it is easier to edit it in VSCode as XML than on the visual editors.

XML is not the most legible format. If we could edit these as JSON or YAML, it would make editing it a lot easier. Not sure how one would declare CDATA type content on JSON or YAML, but this more in the detail of development.

It will also make diffs on source control easier to interpret and correct.
