 Vertices, faces and (half-)edges need the OpenMesh::Attributes::Status attribute
 which is used to hold the flag "deleted" if an element is deleted.
 
-The struct which defines the mesh traits then looks like this:
+Instead of defining the required attributes via traits on compile-time, it is possible to request
+attributes dynamically on run-time by requesting them.
+In this example, we want to delete faces, edges and vertices, therefore requesting the status attribute is required.
+\note You have to request attributes before you use them, if you don't enable them via traits.

 After having created the geometry of the cube one can delete faces and vertices
 by simply calling delete_vertices() (delete_faces() or delete_edges() respectively).
