RE: Heading levels

From: Jon Gunderson

The functional accessibility evaluator [1] allows any heading
level before the last H1 element (Note: H1 are reserved for
titling pages and the last H1 is considered the sub page title
of a page [2]). After the last H1 the heading should use
hierarchical structure. H2 should also be used to label
navigation bars[3], so there maybe h2 before the first H1 element.
