interface nsISAXContentHandler : nsISupports

/**
 * Receive notification of the logical content of a document.
 *
 * This is the main interface that most SAX applications implement: if
 * the application needs to be informed of basic parsing events, it
 * implements this interface and registers an instance with the SAX
 * parser.  The parser uses the instance to report basic
 * document-related events like the start and end of elements and
 * character data.
 *
 * The order of events in this interface is very important, and
 * mirrors the order of information in the document itself.  For
 * example, all of an element's content (character data, processing
 * instructions, and/or subelements) will appear, in order, between
 * the startElement event and the corresponding endElement event.

   * The Parser will invoke this method at the beginning of every

   *
   * This event allows up to three name components for each element:

   * 2.) the local name; and
   * 3.) the qualified (prefixed) name.
   *
   * Any or all of these may be provided, depending on the values of
   * the http://xml.org/sax/features/namespaces and the
   * http://xml.org/sax/features/namespace-prefixes properties:
   *
   * The Namespace URI and local name are required when the namespaces
   * property is true (the default), and are optional when the
   * namespaces property is false (if one is specified, both must be);
   *

   * property is true, and is optional when the namespace-prefixes
   * property is false (the default).

   * contain attributes used for Namespace declarations (xmlns*
   * attributes) only if the
   * http://xml.org/sax/features/namespace-prefixes property is true
   * (it is false by default, and support for a true value is
   * optional).

   * @param uri the Namespace URI, or the empty string if the
   *        element has no Namespace URI or if Namespace
   *        processing is not being performed
   * @param localName the local name (without prefix), or the
   *        empty string if Namespace processing is not being

   * @param qName the qualified name (with prefix), or the
   *        empty string if qualified names are not available
   * @param atts the attributes attached to the element.  If
