Data mapping question

Question

I was excited to see this https://forum.plantuml.net/13337/data-mapping-visualisation 

I'd like to check if this can work when I have indented elements. How would I make the following mapping work?

@plantuml is this something that should work? How can I link to a specific property once I have added the |_ notation?

I don't think I can alias the property, so any idea would be appreciated

Trying to get some help on this, as mapping is increasingly useful in our open specification process, and it could allow us replace the current mapping display (a cumbersome tool) and just use plantuml for everything. I'm glad to learn and do a PR if I could get some help to where in the code the elements are identified, and how the tree display is generated.

Alternatively, if we could also get the tree rendered by using some dot notation - then we could use the dot notation. Example, the Output class above would have these elements:

identifier
result
something
something.type
something.value
somethingElse
