Ok; then to keep things very simple, we can have a simple editor which potentially can be a table/tabletree like properties view; however with 4 columns instead of 2, viz, key, value, type and description. I bring up tabletree as an option, incase you want the hierarchy to be visible, which I think can be important because the file is a xml and I saw it having a good nested structure.

Agree. We need to also have the "type" and "description" information
along with key/value. Value and description values are optional.
