If you maintain (as I do) that the first <h1> is the document's title --
the same as the <title> element but without the requirement that it be
phrased so that it can be quoted out of context -- then yes. The first
section is the <body>, the <body> is the document's content, and the spec
# The first heading in a sectioning element gives the header for that
The content at the top of the <body> is part of the <body>, and thus it is
associated with the <body>'s heading.
Why would you _not_ want the navigation links, or the byline, or the
dedication, etc, to be associated with the document's first section? It
seems correct to me.

Do you have any examples? As far as I can tell we always want the first
heading of a section (assuming it isn't preceeded by any subsections) to
be the heading of the section.

But this will be happening all over the place.
<p>Fox Publications Presents:</p>
<h1>The Big Newspaper</h1>
<h2>Flood in town</h3>
The first <p> is clearly part of the same section as the first <h1>. The
whitespace node before the two <h2> elements are similarly obviously part
of their <section>, and the <h2>s clearly don't start a separate section
that is independent of the <article> and <section> elements.

Because the spec is defined in terms of nodes, and introducing special
rules for nodes that only contain space characters is a recipe for
confusion and lack of interoperability (I'm talking from experience here).

It might well be rendered (e.g. due to 'whitespace: pre').

I am suggesting that, and by extension, I'm suggesting that the first node
(whatever it is) be associated with te first section, and that that be
associated with the first heading.
