Chapter 10. Iteration 7: Adding an RSS Web Feed

In the previous iteration, we added the ability for the user to leave comments on issues and to display a list of these comments utilizing a portlet architecture to allow us to easily and consistently display that listing anywhere throughout the application. In this iteration, we are going to build upon this feature and expose this list of comments as an RSS data feed. Furthermore, we are going to use the existing feed functionality available in another open source framework, the Zend Framework, to demonstrate just how easy it is for a Yii application to integrate with other third-party tools.
