Ian, I've moved this to "other" in response to your request, but I suppose it could also go into "developers non-staining" if you think it might get more attention there. Let me know if you have a preference.

[David A. Goldfarb]

Okay. Moved again to "developers non-staining" to fit with other reversal processes.
