<p dir="ltr">Note that the closest subsequent point is likely to be a parent array, since objects don't hold objects (they hold objects as values of attributes). Is this what we want? As to finding the parent array, I was thinking each object could contain a "../arrayElement" attribute which would have a value of the JSONPath from the root to the array element index that the ProtoInstance (for example) is contained within. Doing this with nested protoinstances could get really tricky. I almost want to do the Proto expansion first, and then try to add the switch nodes in the Flattener.js. hmm. That may work a lot better. Thank you John for thinking this through before implementation. </p>
