"Semantic" group limited to HTML5 additions

[fvsch]

Of course many HTML elements have "semantics", but those who are not special-purpose (form elements, media elements…) and are used to group or mark content with meaning include:

• blockquote
• h1 … h6
• abbr, cite (not less semantic than time)
• em, strong
• etc.

Maybe this section could be replaced by a "Structure" section that focuses on elements used to describe the structure of a document or app, whether they are HTML4 or HTML5 elements. That would include things like:

• head, body (could be useful)
• h1 … h6
• header, footer, main, section, aside, article
• nav

And maybe leave out figure, figcaption, mark, time, blockquote.
