What feature do you want?

I would like News to ignore CDATA issues when loading an OPML file. The kind of CDATA issue News rejects looks like this:

<description><![CDATA[				<![CDATA[]]>]]></description>

Such issue exists in the feed available here: http://exple.tive.org/blarg/feed/

Why do you want this feature?

I understand that News is in fact correct to point out this issue, but I would still like the feed to be imported. Indeed, having an article the description of which is ]]> would be an improvement over not having any articles at all.
