     * Parse an RSS 1.0 feed and display titles
     *
     * The example demonstrates fetching an RSS 1.0 feed from the
     * web and then parsing as RDF/XML. The channel is found by getting
     * the first object of type rss:channel (a file should only contain
     * a single RSS channel).
     *
     * In RSS 1.0, the list of items in the feed are listed by relating
     * the rss:channel to the rss:items using an rdf:Seq. In EasyRdf
     * this maps into an EasyRdf\Container object, which can be
     * iterated over using a foreach() loop.
     *
     * Note that this example only works with RSS 1.0 and no
     * other version (0.90, 1.1 and 2.0) as they are not RDF.
