           Summary: Making the main content element a sectioning element

          Severity: normal
    Classification: Unclassified
                OS: Windows NT

Because both being elements for content, it is inconsistent that complementary
content is sectioning element and main content is not.

Another reason is about document outline. Please take a look at the markup
below:

<!DOCTYPE html>
<title>blablabla</title>
<header>
    <h1>Branding</h1>
    <nav>
        <h1>Navigation</h1>
        blablabla
    </nav>
    <aside>
        <h1>Search</h1>
        blablabla
    </aside>
</header>
<main role="main">
    <h1>Main Content</h1>
    <section>
        <h1>Welcome</h1>
        blablabla
    </section>
    <section>
        <h1>Brief Intro</h1>
        blablabla
    </section>
</main>
<aside role="complementary">
    <h1>Complementary Content</h1>
    <article>
        <h1>Latest News</h1>
        blablabla
    </article>
    <article>
        <h1>Recent Comments</h1>
        blablabla
    </article>
</aside>
<footer>
    blablabla
</footer>


If the main content element is a sectioning element, the document outline
formed by the above code will be clear and hierarchically correct:

1. Branding
        1. Navigation
        2. Search
        3. Main Content
                1. Welcome
                2. Brief Intro
        4. Complementary Content
                1. Latest News
                2. Recent Comments


But if the the main content element is not a sectioning element, the document
outline will be confusing and hierarchically incorrect:

1. Branding
        1. Navigation
        2. Search
2. Main Content
        1. Welcome
        2. Brief Intro
        3. Complementary Content
                1. Latest News
                2. Recent Comments


Both main content and complementary content are content, so they are supposed
to be at the same level in document outline.
