in re: Scheme Legend

These are all good solutions, but to other great puzzles different from this one. E.g. puzzle for solutions using the DMS and VCV schemes could be formulated as "Find a J phrase for which (-: ".^:_) is true". -- Oleg Kobchenko <<DateTime(2005-11-07T19:12:08Z)>>

Very good clasification by Dan Bron. PMF is also a different puzzle. The original problem still being sought is categorized as SPI -- Oleg Kobchenko <<DateTime(2005-11-08T20:54:41Z)>>

Then again, SPI solutions can be derived from self-reproducing expressions (satisfying (-: ".)) as illustrated by the solution 29 -- Pepe Quintana <<DateTime>>
