如何在RSS源中显示文章链接和子提要链接？

I'm working on some RSS feeds for a custom task system we have. The main feed will show a list of tasks assigned to the current user. The link attribute for each task returned points to the web page for that task. However, tasks themselves have an RSS feed for updates, and I want to be able to provide a link for that RSS feed with the main feed as well. How can I do both?I'm working on some RSS feeds for a custom task
