Sounds alright to me as well.

In GRASS there is already a term "key column" (the column that links the
category number with the table row). Since terms "field" and "column"
are sometimes used interchangeably, and term "key column" is already a
part of GRASS terminology, using "keyfield" for something different will
lead to confussion.

May I suggest "table link" in place of the current "layer" then? So each
vector map can have multilpe "table links", and each "table" can have
it's own "key column".

As to "voxel" and aliases (i.e. "3D raster", "G3D", "volume", "GRID3D",
"3d cell") - could we just stick to "3d raster layer"? A little longish,
but plain obvious and conforms to "(2d) raster layer", "(2d/3d) vector
layer".
