Well, Steve the question as I can best formulate it would be : would 
relcol simply scale L* from media white to BPCted black in a 
linearmanner (the way you linearise the printer output e.g. evenly 
spaced L* intervals) while the perceptual one would include a gamma-
like formula to the restricted L* (L* being scaled only from media 
white to BPCted black instead of 0-100)thus preserving human 
perception and contrast.

Sorry I can't think in XYZ, and all the above probably sounds very 
naive...
