Comment:

 CDATA wrappers should be removed from all templates and applied via
 filters using new functions. There are some complications.

 A quick search for 'the_title_rss' (e.g.) finds that filter tag used in
 wp-admin/includes/export.php, which reminds that we use feed-related
 functions for more than just feeds. Any changes to feed-related filters
 must be tested with export/import.

 The same search also finds the template tag the_title_rss() in feed-
 rss2.php and feed-atom.php, but only CDATA-wrapped in the latter.
 Universal use of CDATA tags to guarantee XML validity is of dubious merit.
 However, if we are going to do it we should be consistent.

 3670-I.diff is the first half of the fix. It will break some feeds (rare)
 so it should not be applied by itself. The second half, installing new
 CDATA filters, touches a lot of code. Please volunteer.
