SyndicationFeed: Content as CDATA?

I'm using .NET's SyndicationFeed to create RSS and ATOM feeds. Unfortunately, I need HTML content in the description element (the Content property of the SyndicationItem) and the formatter automatically encodes the HTML, but I'd rather have the entire description element wrapped in CDATA without encoding the HTML.

My (simple) code:

var feed = new SyndicationFeed("Title", "Description", 
               new Uri("http://someuri.com"));
var items = new List<SyndicationItem>();

var item = new SyndicationItem("Item Title", (string)null, 
               new Uri("http://someitemuri.com"));

item.Content = SyndicationContent.CreateHtmlContent("<b>Item Content</b>");

items.Add(item);
feed.Items = items;

Anybody an idea how I can do this using SyndicationFeed? My last resort is to "manually" create the XML for the feeds, but I'd rather use the built-in SyndicationFeed.

This worked for me:

public class CDataSyndicationContent : TextSyndicationContent
{
    public CDataSyndicationContent(TextSyndicationContent content)
        : base(content)
    {}

    protected override void  WriteContentsTo(System.Xml.XmlWriter writer)
    {
        writer.WriteCData(Text);
    }
}

then you can:

new CDataSyndicationContent(new TextSyndicationContent(content, TextSyndicationContentKind.Html))
