This sitemap of sitemaps contains the links to the sitemaps for each datafeeds menu item. The general syntax for a sitemap for a single menu is

http://website/index.php?option=com_datafeeds&view=items&format=xmlmap&Itemid=<menu id>

site map depth

The sitemap will show an url for each menu on each menu level defined in the menu configuration. Google will not parse sitemaps containing over 50.000 pages. To limit the number of levels added to the sitemap and therefor reducing the number of pages in the sitemap use the parameter depth xml map in the menu configuration
