I'll try to answer this question briefly, because I know you don't have much time.
A priori, there's also an approach establishing a link between the legislative framework and the enforcement framework. I certainly have a vision that is inspired by my training in civil law. We start by implementing coherent principles. Later, there may be more detailed rules, but there is, in a way, a structural organization of rules.
I think that initially, when the law was created in 1986, legislators had an idea in mind and a common thread. We may agree or disagree, but I think over the years things have simply been added, mostly details. This style of drafting is fairly typical of common law countries. Instead of stating the general principle, we're afraid, so we make lists.
The problem is that, subsequently, the lists influence the way the general provision is interpreted.
