I'm struggling to understand the reasons for <hgroup>: wouldn't one or

To illustrate my query, what is the difference between
<header>
<h1>HTML 5</h1>
<h2>a new era of loveliness</h2>
<nav> ... </nav>
</header>
and
<header>
<hgroup>
<h1>HTML 5</h1>
<h2>a new era of loveliness</h2>
</hgroup>
<nav> ... </nav>
</header>
<hgroup> affects the document structure, <header> does not. So if you
made an outline view of your document, the examples above would look
(with the addition of a <hx> element inside the nav with content
"Navigation") like
+--HTML 5
+--A new era of loveliness
+--Navigation
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?
+--HTML 5 - a new era of loveliness
+--Navigation
So, in the first example "A new era of loveliness" is a real section
heading and the navigation becomes a subsection of that section. In the
second example the <hgroup> element tells us that the <h1> and <h2>
elements form a heading-subheading pair and that the navigation is a
subsection of the section headed by this heading/subheading pair.
Is that any clearer?
