[Property] edge [Optionality] Optional [Description] Because a passive continental boundary often tends to be broad and hard to pin down, it is expected that users may wish to distinguish between an "inner" and "outer" passive continental boundary. The property is used to indicate whether the feature is an "inner" continental boundary, meaning the edge of the continental boundary that is closer to the center of continetal crust, or an "outer" continental boundary, meaning the edge of the continental boundary that is farthest away from the center of continental crust.
