Response to Ilfosol S = Xtol?

I remember reading something in the Film Developing Cookbook about the two develoeprs not being the same. There still seems to be some amount of disagreement about ascorbic acid as a developing agent and its exact nature of functioning. The designer of XTOL (and Anchell and Troop seem to agree) says ascorbic acid is the primary developer in XTOL. However, in Ilfosol-S, Anchell and Troop suggest that the ascorbic acid is being used to enhance other developing agents - I think this may have been under the ascorbic acid and the environment section. Cheers, DJ.
