It is indeed not kodalith. If I remember correctly, the proportion of chemicals used is different. I have used both. For my application at that time, it didn't make much difference.

For application in photopolymer, I think diluted kodalith and stand development might work fine.The stand development will give the nice, crisp edge because of local exhaustion; but the dilution must be done just prior to development, otherwise the developer might be exhausted too quickly.

  I've still not found the recipe/formula . . but, Kodak's info states it is not a substitute for Kodalith developer. Kodak says, "By using Kodalith Fine Line Developer, the loss of highlight and shadow contrast can be avoided comletely. Halftone can be copied as strait line work, without re-screening, giving reproductions of much better quality."
  You use Ortho Film, Type 2 exposed for 75% of the normal time for it when using Kodalith developer. "Place face up in Fine Line Developer, agitate for 20 seconds until a faint image appears, press to bottom of tray (glass is preferred) and allow to develop w/out agitation for a total time of 2 - 2/12 minutes."
  "At the very end of the development period, the negative may be held up for examination for a few seconds. Here Kodak recommends the glass tray w/safelight underneath. Best results are obtained, at least for lithographic printing, with negatives that appear rather dark."

  The other way of getting similar effect with fine line developer is to
  dilute kodalith and do still development (agitate for the first minute and
  then let it stand for the remaining development time).
