When it comes to renewal, a lot of that is based on the priority welfare issues of the day. Looking at the last time the code was done, there's usually a list of some of the hard topics or some of the areas where the science was lacking. Perhaps we wanted to make a decision on an issue but we looked for research on it and it wasn't there. The next time, we ask whether there has been any new stuff since. Has there been any research that's come out since the last one that should change it? It's an environmental scan of what the practices are now, what research has been done since, what was hanging from the last code, and it's a lot—
