I found some URLs in the generated Sitemap, which lead to disabled Pages and thus generate a 404 Errror, i updated this page (enabled and disabled Page Content aswell as the Page itself) to see if the sitemap would update the lastmod-Timestamp, after flushing the Cache i could see that the new Date was shown in the lastmod section of the url.
But the URL should be removed from the Sitemap, because the Page does not exist.
The Page itself is a alternative Language Page to an existent Page which has content and is online. It was removed because it had no Content for the selected Language.
