Consider the following document:

  <div>
  <h1>Section</h1>

  <p>This is the <em>first</em> section.</p>
  </div>

Without the start/end callbacks, you wouldn't be able to figure out
the nesting of the document, or even the real order of the character
data:

  element("div", "\n\n\n\n")
  element("h1", "Section")
  element("p", "This is the  section.")
  element("em", "first")


All the best,


David
