I just wanted to go back a little bit to your comments regarding performance rather than method on the regulations and how that would work out in essentially an outcome-based solution. Rather than looking at regulations that say, “This is how you have to get to this point”, you're saying that you just want to work with the regulatory bodies to say, “This is the outcome we want, and this is required performance”, and then work within the context of that to get to that.
You gave us one example of that, but as you go through the process of your development, are you able to work with some of the regulatory bodies? You obviously worked through one of these situations. Is that something that is an ongoing process, where you're working with the regulatory body to try to change that mindset, and also to show, as you're going through the process, the capabilities you have, the changing capabilities, and how they can be adjusted to bring forward better performance in the end, without having to rely completely on a system where we're looking at everything from a methodology point of view rather than a performance point of view?
