How to show a selection adornment only on a part of the selected node

Since there are two properties, “adornedPart” and “adornedObject” it seems that it is possible to show an adornment around a certain graphical object of a node. Maybe this is related to the “locationObjectName”? However, I can’t figure out how it is done. I’m trying to show a selection adornment only around one graphical element of a node and not around graphical elements outside the “core” of the node. Is this possible?

You can use Part.selectionObjectName.
