validating a feed

[Jim Alateras]

Just wondering what the best way is to validate an atom feed. Currently 
I do the following

Abdera abdera = new Abdera();
Parser parser = abdera.getParser();
Document<Feed> feed = parser.parse(
 new StringReader(response.getEntity().getText()));
but it still seems to create a valid document even if i parse an RSS 
document, like the one below

<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:content="http://purl.org/rss/1.0/modules/content/"; 
xmlns:georss="http://www.georss.org/georss"; xmlns:taxo="http://purl.or
