For c14n? I don't have any development docs, no. You'd have to look at what's there.

It might be just as useful for me to implement a simple regex enforcement setting in all the ValidateXX actions in the base class, though. That would certainly knock this out globally.

I think your use case is better handled inline by having the validate actions just raise an UnknownPrincipal error event based on a regex. Should be simple enough, just file a RFE.
