Help with RSS Auto Discovery in Browser

I’ve been doing web dev for years, but this is my first jump into XML. I’ve created an RSS feed and I cannot figure out how to get the browser to “discover” my feed and display the little RSS icon in the address bar. The website in question is: http://www.aurorafxstudios.com/blog.php and my RSS feed is at: http://www.aurorafxstudios.com/blog.xml …any help would be greatly appreciated. Thank you!

If you hit view source on this page you would see:

<link rel=“alternate” type=“application/rss+xml” title=“SitePoint Forums - General Web Development & Application Design Issues - RSS Feed” href=“http://www.sitepoint.com/forums/external.php?type=RSS2&amp;forumids=140” />

Which provides the template . . .
