It is a bit more than that; I think it only really makes sense if you 
have two or more variogram components besides the nugget. It is not so 
hard to do, but I'm afraid none of the package developers has felt the 
urge to do so. Even nested variograms, e.g. with two spherical models, 
are afaik only found in one package, but I may be wrong there.
