This means that all other keys except profile will have no effect. +-# content-url - Location of the security content. The content must be accessible using HTTP, HTTPS, or FTP; local storage is currently not supported. A network connection must be available to reach content definitions in a remote location. +-# datastream-id - ID of the data stream referenced in the content-url value.
