HTML sections (<section>) normally include a heading (<h1> etc)

On the page for the doc of a type (class, interface, etc) the primary content of the page begins with a header and heading, followed by a section that contains the content derived from the doc comment for the type.

While there might be a bigger discussion about how to mark/enclose content derived from the doc comment, a short term solution would be to move the <section> tag "up a bit. In terms of the HTML file, this is literally moving "<section> up a few lines; in terms of the tree structure, it means moving it up a few nodes if possible, or else moving the header/heading down into the section.
