As i already mentioned, i know about sitemap tab and interwoven components and that they use default.sitemap. default.sitemap file has a simple and intuitive xml structure but yes i agree, it is Not Recommended to edit it manually. The query really is :1. Would like to know specific details on how Sitemap is a "key" component?2. What all Teamsite Product Lines are based on it? lets say, has 'Targeting' any dependency on SiteMap. etc3. How does sitemap fit into 'big picture' ?
