Specific RSS Feed can't be displayed

[nukulaar]

Imported all my Google Reader feeds, but one failed:

See http://feedvalidator.org/check.cgi?url=http%3A%2F%2Ftools.cisco.com%2Fsecurity%2Fcenter%2Fpsirtrss20%2FCiscoSecurityAdvisory.xml

Unfortunately the feed does not validate. To fix this either contact the admin at Cisco to fix their feed or file an issue in the repo of the rss library that we use: https://github.com/simplepie/simplepie
