Well, the real answer to that is an entire lecture that I deliver, which obviously you don't have the time to hear. But it's safe to say there are some very well-developed methodologies, including those by UN experts, that are now well accepted and recognized as providing a comprehensive approach with regard to the range of human rights that are assessed, the scope of consultation, and the frequency and regularity of assessments that are carried out. There's some flexibility around that depending on the deal, depending on the scope of the deal, and depending on the countries that are involved, but there is a lot of information to draw on.
