+ * This class provides a way to translate three representations of
+ * XML data (SAX event stream, DOM tree, and XML text) into each other.
+ * In essence it's a thinnish wrapper around basic SAX event
+ * <a href="../pipeline/package-summary.html">pipeline</a> facilities, which
+ * exposes only limited functionality.  The <em>javax.xml.transform</em>
+ * functionality is implemented as follows: <ul>
+ *
+ * <li>The {@link javax.xml.transform.sax.SAXSource SAXSource} class
+ * just wraps an {@link XMLReader} and {@link InputSource}, while the
+ * {@link javax.xml.transform.sax.SAXResult SAXResult} class is less
+ * functional than a {@link gnu.xml.pipeline.EventConsumer EventConsumer}.
+ * (Notably, it drops all but one declaration from any DTD.)</li>
+ *
+ * <li>The {@link javax.xml.transform.dom.DOMSource DOMSource} class
+ * corresponds to special SAX parsers like {@link DomParser}, and the
+ * {@link javax.xml.transform.dom.DOMResult DOMResult} class corresponds
+ * to a {@link gnu.xml.pipeline.DomConsumer DomConsumer}.</li>
+ *
+ * <li>The {@link javax.xml.transform.stream.StreamSource StreamSource}
+ * class corresponds to a SAX {@link InputSource}, and the
+ * {@link javax.xml.transform.stream.StreamResult StreamResult} class
+ * corresponds to a {@link gnu.xml.pipeline.TextConsumer TextConsumer}.</li>
+ *
+ * </ul>
+ *
+ * <p><em>This implementation is preliminary.</em>
