Dave,

   Well, I consider layers to be the third dimension in GRASS vector object
geometry. They are not independent geometrically if we think of them as
'themes,' each mapping objects of the same type, and yet that theme/layer
has positional relationhips (geometry) with other layer which is usually
where our interest lies.
