If a view is available in HTML and feed formats, you might want to add a link in the
HTML view to the feed view. We can use the HTML link tag to define an alternative
way of viewing data. This example shows how we can add such a tag to the HTML
header. This code should be located in the view class's display() method.
// build links
$feed = 'index.php?option=com_myextension&format=feed';
$rss = array(
'type' => 'application/rss+xml',
'title' => 'My Extension RSS Feed'
);
$atom = array(
'type' => 'application/atom+xml',
'title' => 'My Extension Atom Feed'
);

// add the links
$document =& JFactory::getDocument();
$document->addHeadLink(JRoute::_($feed.'&type=rss'), 'alternate',
'rel', $rss);
$document->addHeadLink(JRoute::_($feed.
