  27  * Provides stream and URI specific transformation classes. 
  28  * 
  29  * <p>
  30  * The {@link javax.xml.transform.stream.StreamSource} class
  31  * provides methods for specifying {@link java.io.InputStream} input,
  32  * {@link java.io.Reader} input, and URL input in the form of strings. Even
  33  * if an input stream or reader is specified as the source,
  34  * {@link javax.xml.transform.stream.StreamSource#setSystemId} should still
  35  * be called, so that the transformer can know from where it should resolve
  36  * relative URIs. The public identifier is always optional: if the application
  37  * writer includes one, it will be provided as part of the
  38  * {@link javax.xml.transform.SourceLocator} information.
  39  * <p>
  40  * The {@link javax.xml.transform.stream.StreamResult} class
  41  * provides methods for specifying {@link java.io.OutputStream},
  42  * {@link java.io.Writer}, or an output system ID, as the output of the
  43  * transformation result.
  44  * <p>
  45  * Normally streams should be used rather than readers or writers, for
  46  * both the Source and Result, since readers and writers already have the encoding
  47  * established to and from the internal Unicode format. However, there are times
  48  * when it is useful to write to a character stream, such as when using a
  49  * StringWriter in order to write to a String, or in the case of reading source
  50  * XML from a StringReader.
  51  *
