+/**
+ * XListMenu class
+ *
+ * XListMenu displays a list of hyperlinks that can be used for page menus.
+ * Menu items adjust their css class automatically according to the current
+ * page displayed. In particular, a menu item is considered as active if
+ * the URL it represents is for the page currently displayed.
+ *
+ * Usage of XListMenu is similar to PRADO list controls. Each list item has
+ * two extra properties: {@link XListMenuItem::setPagePath PagePath} and
+ * {@link XListMenuItem::setNavigateUrl NavigateUrl}. The former is used to
+ * determine if the item is active or not, while the latter specifies the
+ * URL for the item. If the latter is not specified, a URL to the page is
+ * generated automatically.
+ *
+ * In template, you may use the following tags to specify a menu:
+ * <code>
+ *   <com:XListMenu ActiveCssClass="class1" InactiveCssClass="class2">
+ *      <com:XListMenuItem Text="Menu 1" PagePath="Page1" />
+ *      <com:XListMenuItem Text="Menu 2" PagePath="Page2" NavigateUrl="/page2" />
+ *   </com:XListMenu>
+ * </code>
