Example: accessibility problems

• A sighted person "sees" the structure
• A non-sighted person cannot
  • the structure must be present in the markup
• Text would also benefit from such a treatment
  • not h1, h2 etc (which are subject to misuse) but
  • nested sections with their own headings

    <section>

        <h>XHTML</h>

        ...

        <section>

           <h>Structure</h>

           ...

        </section>

    </section>
