WordPress remove namespace part from my tags in rss feed

    I’m making a custom rss feed, with which outputs tags in particular namespaces. But when i output <pugpig:summary> for example, the pugpig part disappears and i’m left with <summary> in the output tag. How is wordpress doing this and how can i stop it.

    Here is my custom feed logic

    add_action(‘init’, ‘ns_add_custom_rss_feeds’);

    function ns_add_custom_rss_feeds(){
    ns_create_pugpig_feed();
    ns_create_content_feed();
    ns_create_issue_feed();
    ns_create_google_currents_feed();
    }

    /**
    * Create the new pugpig feed
    * add_feed params: feed name and callback funcion
    */
    function ns_create_pugpig_feed(){
    add_feed(‘pugpig’, ‘ns_get_pugpig_template’);
    }

    /**
    * Callback function to create the feed
    * get_template_part link to a separate template file to keep the functionality separate to the layout.
    * the file will be: /wp-content/themes/template/rss-pugpig.php
    */
    function ns_get_pugpig_template(){
    get_template_part(‘rss2’, ‘pugpig’);
    }

    And here is where i output the tags

    themes/mythemes/rss2-pugpig.php
    <?php
    /**
    * RSS2 Feed Template for displaying pugpig feed.
    *
    * @package newscientist
    */

    //URL: http://www.newscientist.com/feed/pugpig (for current issue)
    //URL: http://www.newscientist.com/feed/pugpig?issue=1234 (for a given issue)

    $issue = get_query_var( ‘issue’ );

    if(empty($issue)){
    //if the parameter “issue” is not in the URL, we take the current issue
    $issue = ns_get_current_issue_number();
    }

    $issue_info = ns_get_issue_info($issue);
    $volume = $issue_info -> field(‘volume’);

    $args = array(
    ‘post_type’ => ‘article’,
    ‘meta_query’ => array(
    array(
    ‘key’ => ‘issue_number’,
    ‘value’ => $issue
    ),
    array(
    ‘key’ => ‘pugpig’,
    ‘value’ => ‘1’
    )
    ),
    ‘posts_per_page’=>-1
    );
    //query posts by type, issue_number and pugpig flag
    $posts = query_posts( $args );
