## Definition

The concept `AosLandmarkTraits_2` refines the traits concepts `AosApproximatePointTraits_2` and `AosConstructXMonotoneCurveTraits_2`. The type of an arrangement associated with the landmark point-location strategy (see `CGAL::Arr_landmarks_point_location`) must be an instance of the `CGAL::Arrangement_2<Traits,Dcel>` class template, where the Traits parameter is substituted by a model of this concept.
