ClipNode exists to provide a mechanism for the OSG's cull traversal to record the modelview matrix which to apply ClipPlane associated with that ClipNode. ClipPlanes have to applied with a specific modelview matrix in OpenGL which is what makes it "positional state". osg::LightSource + osg::Light work, TexGenNode and osg::TexGen in a similar way as they both require a specific modelview matrix. See the osgclip example to see ClipNode in action.
