 ''unallowed entities''? there are no ''unallowed entities'' in CDATA.
 infact there are not entities at all in CDATA that's why it is used there.
 This is by intention not by mistake. For example if you've got the term
 "&nbsp;" in a posts title it should be in the RSS-Feeds title as well.
 Currently it is not. After the patch it is.
