To be honest, I don't think we ever articulated the principle, or proceeded from it. However, the discussion over Ideographic Space, U+3000, was long and agonized, thus the decision to omit it from the production for "S" was not lightly taken at all. It's hard to see how you could let in U+0085 without letting in ideospace and a bunch more characters that have in some respect the characteristics of white-space-ness. Someone sent me a note offline giving a long list of such items, and it's pretty clear that letting in U+0085 could start us down a slippery slope. Note (although no processor other than Lark ever did this as far as I know) that if you want to build a DFA-based XML processor, you can use the trick of recognizing all the syntax characters with a 7-bit state table and a remarkably small amount of clever sidestepping is required to deal with all the non-ASCII characters. -Tim
