  /**
   * TargetFactory for {@link org.apache.log.output.io.StreamTarget}.
   *
   * This factory is able to create different StreamTargets according to the following
   * configuration syntax:
   * <pre>
   * &lt;stream id="foo"&gt;
   *  &lt;stream&gt;<i>stream-context-name</i>&lt;/stream&gt;
   *  &lt;format type="<i>raw|pattern|extended|xml|cocoon</i>"&gt;<i>pattern to be used if needed</i>&lt;/format&gt;
   * &lt;/stream&gt;
   * </pre>
   *
   * <p>The "stream-context-name" is the name of an <code>java.io.OutputStream</code> that
   * is fetched in the context. This context contains two predefined streams :
   * <li>"<code>System.out</code>" for the system output stream,</li>
   * <li>"<code>System.err</code>" for the system error stream.</li>
   * </p>
   *
   * <p>The syntax of "format" is the same as in <code>CocoonTargetFactory</code>.</p>
