Broken RSS feeds in CMSB

I just discovered my RSS feeds were broken. I was getting the error messages at the bottom of this post when trying to view them in a browser or load them to my.yahoo, google, etc.

I went back and checked and I've followed your example (http://www.interactivetools.com/docs/cmsbuilder/rss_feeds.html) perfectly. They also worked when originally posted to my site.

However once I removed the top line declaration statement: <?php header('Content-type: application/xml; charset=utf-8'); ?><?php echo '<?xml version="1.0" encoding="UTF-8"?>'; ?>

The pages loads normally again- which seems wrong because I thought the declaration statement was required.

Thoughts?
