The ItemText property returns a string that contains a
          summary of the current news item. This may property may return either
          plain text or HTML formatted text. If no text has been specified for
          the current item, this property will return an empty string. Although
          it is not required for a news item to have a description, a feed that
          conforms to the standard must have either a description of the item
          or a title, which is returned by the ItemTitle property.
