/***********************************************************************************************************************
 *
 * &lt;p&gt;A default implementation of the {@link SitemapViewController} that is independent of the presentation technology.
 * This class is capable to render the sitemap of a {@link Site}.&lt;/p&gt;
 *
 * &lt;p&gt;Supported properties of any {@link SiteNode} in the site:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@code P_SITEMAP_PRIORITY}: the priority of the {@code SiteNode} - if zero, the node is ignored;&lt;/li&gt;
 * &lt;li&gt;{@code P_SITEMAP_CHILDREN_PRIORITY}: same as {@code P_SITEMAP_PRIORITY}, but for child nodes;&lt;/li&gt;
 * &lt;li&gt;{@code P_LATEST_MODIFICATION_DATE}: the date-time of the latest modification;&lt;/li&gt;
 * &lt;li&gt;{@code P_SITEMAP_CHANGE_FREQUENCY}: the supposed change frequency of the {@code SiteNode}.&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;Concrete implementations must provide one method for rendering the calendar:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@link #render(java.util.List)}&lt;/li&gt;
