rss feed won't validate when I use the element?
I'm trying to use the <itunes:order> element -
http://deimos.apple.com/rsrc/doc/iTunesUAdministrationGuide/AddingContent/chapte r12_section3.html
When I run my feed through the W3C rss validator it won't validate. It says - Undefined item element: itunes:order
I also get a recommendation which says - Use of unknown namespace: http://www.itunesu.com/feed
As far as I can tell I'm doing everything correctly. The iTunes and iTunesU namespaces are declared correctly in the root rss element and the itunes:order are where they should be within the <item></item> element.
What am I doing wrong? Any help would be much appreciated.
Here's my rss feed -
