Do you need to put ads on sitemaps? I use the auto generated sitemap from http://www.xml-sitemaps.com/ which unfortunatly isnt easy at all to add the ads and it can be pretty annoying.
I can't confirm 100% ... but I don't believe so. If it is remotely hosted. If it is hosted on your site, or a page directly on your site, then I believe so.
But, my opnion, is no. ( Another mod / admin maybe can clarify )
