Sodium Oxalate recipe and Cyanotype Rex

Loris, thank you very much for the speed answer.
I am curious about your final report about using Cyanotype Rex, if you finish your test.
David Hatton's letter cool a bit my intentions to try CRex.

Stane, you may use sodium carbonate and citric acid -> sodium citrate. It
works perfectly as a Kallitype developer (20%).

See http://www.usask.ca/lists/alt-photo-process/2002/jan02/0292.htm to learn
how to make sodium citrate from sodium carbonate and citric acid.

What about sodium oxalate? Is it OK as Pt or Kallitype developer?
I can get here sodium carbonate much cheaper than potassium one.
