I wouldn't say it's voluntary because Treasury Board, as an organization, has the authority to issue policy and it's up to the departments to comply with that policy. All I'll say in the narrative is it's early days still, but we've noticed substantial improvement in the content as we've moved to standardize RPPs as well as what's in the estimates. Really, I think I can just leave it at that.
