     [`CGAL::Sizing_field_with_aabb_tree`](https://doc.cgal.org/5.6/Mesh_3/structCGAL_1_1Sizing__field__with__aabb__tree.html),
     a geometry-aware sizing field for feature edges in polyhedral domains.
 -   Added new meshing criterion
-    [`edge_min_size`](TODO)
-    to avoid subdividing sharp edges that are shorter than the prescribed size bound.
