Section element - Example error

Hello,

I see that there is a mistake on the section element (
http://www.w3.org/TR/html5/sections.html#the-section-element) in the last
code example about the book authors. You can see that the CSS used for
render headings is an h1 element, but on the HTML it is using an h3
element. So maybe the correct for CSS is "section.chapter *h3*" and
"section.appendix
*h3*".

Yours faithfully
