Feed will also support the media rss spec as part of our RSS parsing. This allows a nice way to provide links to assets (images, video, etc) within the rss feed in a standardized way.
This requires the tag to add additional XML namespaces (xmlns:media).
These are used within an RSS feed like so:
<?xml version="1.0"?>
<rss version="2.0"
xmlns:xcal="urn:ietf:params:xml:ns:xcal"
