Where is my xml

Most of the Extensible Markup Language (XML) elements of an RSS 2.0 feed are available as read-only properties on the associated objects.
Although some channel elements (such as cloud, rating, skipDays, and skipHours) are not available as properties on the IFeed interface, they are still in the XML source for the feed. Additional namespace extensions define properties that are used by the Windows RSS Platform to manage lists. (See Simple List Extensions.)
