The basic idea is to check for every edge that's part of the selection whether both its polygons are also part of the selection. For the edge to be an outline edge, only one of its polygons may be part of the selection.
Looking at it again, I noticed that the two Filter nodes behind EdgeToCWPolygon and EdgeToCCWPolygon are unnecessary (both pipes can plug directly into Find in Array without a Filter), which makes the compound a bit easier to understand.
