- * </blockquote>
- *
- * <p>This class encapsulates the logic of Namespace processing:
- * it tracks the declarations currently in force for each context
- * and automatically processes qualified XML 1.0 names into their
- * Namespace parts; it can also be used in reverse for generating
- * XML 1.0 from Namespaces.</p>
- *
- * <p>Namespace support objects are reusable, but the reset method
- * must be invoked between each session.</p>
- *
- * <p>Here is a simple session:</p>
- *
- * <pre>
- * String parts[] = new String[3];
- * NamespaceSupport support = new NamespaceSupport();
- *
- * support.pushContext();
- * support.declarePrefix("", "http://www.w3.org/1999/xhtml");
- * support.declarePrefix("dc", "http://www.purl.org/dc#");
- *
- * String parts[] = support.processName("p", parts, false);
- * System.out.println("Namespace URI: " + parts[0]);
- * System.out.println("Local name: " + parts[1]);
- * System.out.println("Raw name: " + parts[2]);
-
- * String parts[] = support.processName("dc:title", parts, false);
- * System.out.println("Namespace URI: " + parts[0]);
- * System.out.println("Local name: " + parts[1]);
- * System.out.println("Raw name: " + parts[2]);
-
- * support.popContext();
- * </pre>
- *
- * <p>Note that this class is optimized for the use case where most
- * elements do not contain Namespace declarations: if the same
- * prefix/URI mapping is repeated for each context (for example), this
- * class will be somewhat less efficient.</p>

+ * in the <em>META-INF/services/org.xml.sax.driver</em> file in
+ * jarfiles available to the runtime.</li>
