forward compatible web services

[Thorsten von Eicken]

I just noticed that if I pass an extra parameter to an action the validation complains "Unknown attributes received: [:code] while loading $.params". If I want to build a "forward compatible" service that continues functioning if a client provides new parameters then this doesn't work very well. Is there a way to tell the validator to ignore extra params? (Yes, I know, I could version, but that's not always a practical thing.)
