Correct.  If it has any special characters, CDATA is added rather than 
using HTML entities.  Seems a little cleaner overall to me.

For all content that has not already been resaved, the switch to expat 
will make it work again becuase the HTML entities will no longer be dropped.

For content that has been resaved, the HTML entities will already be 
gone in the saved data so you'll have to tweak those manually.

Hope that helps :)
