Actually that is a big bug in the documentation of the requirements of 
CGAL::Polyhedral_mesh_domain_with_features_3. The polyhedron type that is 
used 
must use the items class template that is in the file 
<CGAL/Mesh_polyhedron_3.h>. The easiest way to satisfy those requirements is 
to use CGAL::Mesh_polyhedron_3<K>::type as polyhedron type.
