Addressing edges of a boundary

General Discussion
1

Hi

I want to address the edges of an internal border (for instance, label=1). Does the label on a border refer to the elements or edges?

To explain better, “NtonEdge” is a boolean that discusses the edges and can be used inside intalledges…
How can I apply intalledges for a specific inner boundary?

I think BoundaryEdge should help us, and writing like

intalledges(
(BoundaryEdge).(1-NtonEdge).…
);
