Actually I believe it would be:
+--HTML 5
+--A new era of loveliness
+--Navigation
This surprised me when I used implicit sections and just wrapped <article>s around news items (which were <h3>s). I expected the outline to be like it was without the <article>:
+--Site heading
+--Page heading
+--News item
...but instead it became (according to your and gsnedders' outliners):
+--Site heading
+--Page heading
+--News item
Maybe the spec should change here to match people's expectations better?
