WHATWG's specifications should establish clear guidelines about how document hierarchy can be indicated.Should a specification also be an authoring course?
I think it's appropriate for HTML5 to define how authors should use the elements it defines, yes. And fortunately it already does that quite a lot, though I suppose it could be improved.
