The "div" element has been relegated to an afterthought (or, near-deprecation)  in the spec in lieu of Sectioning Content elements. However, neither the "div" (4.12.2 The div element) paragraph nor Sectioning Content paragraphs address this. Web authors would benefit from some HTML 5 guidance in the spec.

Suggested copy:

4.4.2 The section element
ADD
"Note: Please notice that the example above does not use the div element: the section elements have replaced generic container divs; the article element and the header element have replaced author-specific divs which may have used id or class attributes."
"Authors are strongly encouraged to use sectioning elements (i.e., article, section, header, nav, aside, address, footer) where semantically identified containers should be used, e.g., section elements for columns and nav elements for navigation, instead of the div element."


4.4.3 The nav element
4.4.4 The article element
4.4.5 The aside element
4.4.7 The header element
4.4.8 The footer element
4.12.2 The div element
