Missing outline attribute: url

Explanation

The Guidelines for validating OPML imply that a "link" outline has an address of some sort. While an actual attribute name is never specified, the example given shows the attribute to be "url".

As confirmation, OPML Validator Beta specifically detects a missing url attribute as an error when the outline type is "link".

Solution

Include the value for the link in a url attribute.
