/**
 * Standard events for HTML5.
 *
 * This is roughly analogous to a SAX2 or expat-style interface.
 * However, it is tuned specifically for HTML5, according to section 8
 * of the HTML5 specification.
 *
 * An event handler receives parser events. For a concrete
 * implementation, see DOMTreeBuilder.
 *
 * Quirks support in the parser is limited to close-in syntax (malformed
 * tags or attributes). Higher order syntax and semantic issues with a
 * document (e.g. mismatched tags, illegal nesting, etc.) are the
 * responsibility of the event handler implementation.
 *
 * See HTML5 spec section 8.2.4

   * IMPORTANT: The parser watches the return value of this event. If this returns
   * an integer, the parser will switch TEXTMODE patters according to the int.
   *
   * This is how the Tree Builder can tell the Tokenizer when a certain tag should
   * cause the parser to go into RAW text mode.
   *
   * The HTML5 standard requires that the builder is the one that initiates this
   * step, and this is the only way short of a circular reference that we can
   * do that.
   *
   * Example: if a startTag even for a `script` name is fired, and the startTag()
   * implementation returns Tokenizer::TEXTMODE_RAW, then the tokenizer will
   * switch into RAW text mode and consume data until it reaches a closing
   * `script` tag.
   *
   * The textmode is automatically reset to Tokenizer::TEXTMODE_NORMAL when the
   * closing tag is encounter. **This behavior may change.**
   *
   * @param string $name
   *            The tag name.

   * @param boolean $selfClosing
   *            An indicator of whether or not this tag is self-closing (<foo/>)
   * @return numeric One of the Tokenizer::TEXTMODE_* constants.
