Display boundary edges of mesh solid

Hi,
is there a way to display only boundary edges of a mesh solid?
Using FaceBoundaryDraw and FaceBoundaryAspect works for TopoDS_Shape, but not for mesh object.
Other graphic libraries get the result working only on opengl shaders parameters, so I'm wondering if there is a way to get this.
Of course I can enable edges, but it's not what I need.
