  16:  *  This interface represents an output destination for data.
  17:  * <p> This interface allows an application to encapsulate information about
  18:  * an output destination in a single object, which may include a URI, a byte
  19:  * stream (possibly with a specified encoding), a base URI, and/or a
  20:  * character stream.
  21:  * <p> The exact definitions of a byte stream and a character stream are
  22:  * binding dependent.
  23:  * <p> The application is expected to provide objects that implement this
  24:  * interface whenever such objects are needed. The application can either
  25:  * provide its own objects that implement this interface, or it can use the
  26:  * generic factory method <code>DOMImplementationLS.createLSOutput()</code>
  27:  * to create objects that implement this interface.
  28:  * <p> The <code>LSSerializer</code> will use the <code>LSOutput</code> object
  29:  * to determine where to serialize the output to. The
  30:  * <code>LSSerializer</code> will look at the different outputs specified in
  31:  * the <code>LSOutput</code> in the following order to know which one to
  32:  * output to, the first one that is not null and not an empty string will be
  33:  * used:
  34:  * <ol>
  35:  * <li> <code>LSOutput.characterStream</code>
  36:  * </li>
  37:  * <li>
  38:  * <code>LSOutput.byteStream</code>
  39:  * </li>
  40:  * <li> <code>LSOutput.systemId</code>
  41:  * </li>
  42:  * </ol>
  43:  * <p> <code>LSOutput</code> objects belong to the application. The DOM
  44:  * implementation will never modify them (though it may make copies and
  45:  * modify the copies, if necessary).
  46:  * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>Document Object Model (DOM) Level 3 Load
  47: and Save Specification</a>.
