 Adding a custom feed for a Custom Post Type via:


 {{{
         //!shiny new rss feeds
         function create_eventsfeed() {
                 load_template( TEMPLATEPATH . '/feeds/events.php');
         }
         add_feed('events', 'create_eventsfeed');
 }}}


 (also tried using "add_action('do_feed_events', 'create_eventsfeed', 10,
 1);")

 The feed generated does have content according to feedvalidator.org but
 also returns 404 Page Not Found. Adding the feed to the feed reader
 results in a broken feed that it can't connect to.

 However, if I add a single Post (having previously moved the "Hello
 World!" post to the trash), the generated feed works even though it has
 nothing to do with Posts as it only draws from a Custom Post Type. As far
 as I could figure, Custom RSS Feeds for Custom Post Types can only be
 generated if there are also regular Posts, even if they are mutually
 exclusive.

 Here's the code I used for the RSS Feed template (taken directly from
 Wordpress — I know Future posts are technically bad for RSS Feeds but it
 didn't work without that either):


 {{{

 /**

 get_option('blog_charset'), true);
 $more = 1;

 echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>';
 ?>
