/**
 * @deprecated As of release 6.0.0, we don't support the loading of
 * zk-label.properties without installing ZK.
 * Used to hook a label locator to locate resources from the servlet context.
 *
 * <p>Note: you don't need to specify this in web.xml if you use ZK
 * because org.zkoss.zk.ui.DHtmlLayoutServlet will register the label locator
 * automatically.
 *
 * <p>If you don't use ZK, you could declare
<pre><code>
<listener>
	<description>Load zk-label.properties from this Web app</description>
	<display-name>Locating zk-label.properties</display-name>
	<listener-class>org.zkoss.web.init.LabelLocatorHook</listener-class>
</listener>
