This namespace is used in the RSS feed for a scripting2 site.
It has a single element, source, which links to the OPML source for the story behind the item.
The OPML version contains all the text of the story, as well as all its formerly-invisible attributes.
This can be used by "reader" apps such as River2, NetNewsWire and Google Reader, and perhaps others, to present the content of the site in interesting and perhaps innovative ways.
There may be other elements in this namespace in the future.
