Message
An <outline> element whose type is "rss" must have an "xmlUrl" attribute.
Explanation
Your feed is missing an attribute required by the OPML guidelines.
Solution
Provide the http address of the feed in the xmlUrl attribute.
This may just be a typo. Attribute names are case-sensitive; make sure you're using the right case.
