-XML_Feed_Parser 1.0.3 is not currently actively maintained, and has
-a nasty bug which breaks getting the feed target link from WordPress
-feeds and possibly others that are RSS2-formatted but include an
- self-link element as well.
-
-Patch from this bug report is included:
-http://pear.php.net/bugs/bug.php?id=16416
-
-If upgrading, be sure that fix is included with the future upgrade!
