*
* <p>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}.</p>
*
* <p>Supported properties of any {@link SiteNode} in the site:</p>
*
* <ul>
* <li>{@code P_SITEMAP_PRIORITY}: the priority of the {@code SiteNode} - if zero, the node is ignored;</li>
* <li>{@code P_SITEMAP_CHILDREN_PRIORITY}: same as {@code P_SITEMAP_PRIORITY}, but for child nodes;</li>
* <li>{@code P_LATEST_MODIFICATION_DATE}: the date-time of the latest modification;</li>
* <li>{@code P_SITEMAP_CHANGE_FREQUENCY}: the supposed change frequency of the {@code SiteNode}.</li>
* </ul>
*
* <p>Concrete implementations must provide one method for rendering the calendar:</p>
*
* <ul>
* <li>{@link #render(java.util.List)}</li>
* </ul>
