At some web sites you visit the bird icon will indicate that the site's policy is unknown, and the policy summary will indicate that it is being displayed for testing purposes only. These sites have posted their privacy policies in the P3P format, but have included a "TEST" element to indicate that the privacy policy is provided for testing purposes only. Generally these sites are still experimenting with P3P and do not want to be bound by a privacy policy until they are certain that it is correct.
