Yes. it is because the post has `<![CDATA[…]]>` in it.  
[Use CDATA in RSS Feed to add HTML and links | Amit Tech Lab - PHP, AJAX, CakePHP,WordPress, Symfony, Drupal, codeIgnitier](https://amittechlab.wordpress.com/2011/03/02/use-cdata-in-rss-feed-to-add-html-and-links/)

This results in something like

```plaintext
<description><![CDATA[… <![CDATA[ …]]> … ]]></description> 

```

The validator / parser doesn’t do nested CDATA well.
