                    411: <p>Elements, attributes, and attribute values in HTML are defined
                    412: (by this specification) to have certain meanings (semantics). For
1.635     mike      413: example, the <code><a href="http://dev.w3.org/html5/spec/single-page.html#the-ol-element" id="ol">ol</a></code> element represents an ordered list, and the
                    414: <code title="attr-lang"><a href="http://dev.w3.org/html5/spec/single-page.html#attr-lang" id="lang_0">lang</a></code> attribute represents the language of the
                    415: content.</p>
1.626     mike      416: <p>These definitions allow HTML processors, such as Web browsers or
                    417: search engines, to present and use documents and applications in a
                    418: wide variety of contexts that the author might not have
                    419: considered.</p>
                    420: <div class="example">
                    421: <p>As a simple example, consider a Web page written by an author
                    422: who only considered desktop computer Web browsers. Because HTML
                    423: conveys <em>meaning</em>, rather than presentation, the same page
                    424: can also be used by a small browser on a mobile phone, without any
                    425: change to the page. Instead of headings being in large letters as
                    426: on the desktop, for example, the browser on the mobile phone might
                    427: use the same size text for the whole the page, but with the
                    428: headings in bold.</p>
                    429: <p>But it goes further than just differences in screen size: the
                    430: same page could equally be used by a blind user using a browser
                    431: based around speech synthesis, which instead of displaying the page
                    432: on a screen, reads the page to the user, e.g. using headphones.
                    433: Instead of large text for the headings, the speech browser might
                    434: use a different volume or a slower voice.</p>
                    435: <p>That's not all, either. Since the browsers know which parts of
                    436: the page are the headings, they can create a document outline that
                    437: the user can use to quickly navigate around the document, using
                    438: keys for "jump to next heading" or "jump to previous heading". Such
                    439: features are especially common with speech browsers, where users
                    440: would otherwise find quickly navigating a page quite difficult.</p>
                    441: <p>Even beyond browsers, software can make use of this information.
                    442: Search engines can use the headings to more effectively index a
                    443: page, or to provide quick links to subsections of the page from
                    444: their results. Tools can use the headings to create a table of
                    445: contents (that is in fact how this very specification's table of
                    446: contents is generated).</p>
                    447: <p>This example has focused on headings, but the same principle
                    448: applies to all of the semantics in HTML.</p>

                    452: purpose, as doing so prevents software from correctly processing
