I am working for a company that wants their podcast on iTunes... The thing is that they want a specific URL destination (and not the link from the RSS feed itself) pointing from the iTunes page. I know that the tag to change on the RSS feed is the <link> tag but iTunes does not validate my RSS feed.

It is a valid RSS Feed so what could be the issue ?

Code looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
<channel>
<atom:link href="http://www.axa.ca/axa-news-feed-QC-EN.rss" rel="self" type="application/rss+xml" />
