 /**
  * Enables messages to be rendered on different pages from which they were set.
  * <p></p>
  * After each phase where messages may be added, this moves the messages
  * from the page-scoped FacesContext to the session-scoped session map.
- *<p></p>
+ * <p></p>
  * Before messages are rendered, this moves the messages from the
  * session-scoped session map back to the page-scoped FacesContext.
- *<p></p>
+ * <p></p>
  * Only global messages, not associated with a particular component, are
  * moved. Component messages cannot be rendered on pages other than the one on
  * which they were added.
- *<p></p>
+ * <p></p>
  * To enable multi-page messages support, add a <code>lifecycle</code> block to your
  * faces-config.xml file. That block should contain a single
  * <code>phase-listener</code> block containing the fully-qualified classname
  * of this file.
