Some time ago I was trying to split DEM levels and it didn't work for 
me. I have assumed, that DEM layers aren't independent. My guess is, 
that in some cases one layer could have references to another layer.

I didn't notice description of that kind of references in Frank's 
document, but I didn't read it thoroughly enough to be sure.
