well, it looks like the sitemap link has probably been added to index.template.php and, if you want to get rid of the xhtml and the wap2 links, you'll probably have to edit them out in the same file...
the RSS is activated in the news section
index.php?action=admin;area=news;sa=settings#xmlnews_enable
Mr. Phil.... it's not a copyright.
it's just the link to the sitemap, which is XML and not readble by normal/non tehcnical humans
