However, in the end it seems to boil down to the spec suggesting to carry the actual-baseline-table, dominant-baseline-identifier, alignment-baseline, alignment-point and baseline-shift as traits and let the renderers do some of the placement calculations. May be "alignment-point" is the closest to what I have called baselineOffset.
