While discussing with Paedu his RSS  feed,  I  learned  something
about  XML's CDATA sections. I already knew the basic facts about
it, but reading definitive sources [0] (as  always)  improved  my
knowledge.

     Within a CDATA section, only the CDEnd string is recog-
     nized as markup, so that left angle brackets and amper-
     sands may occur in their literal form;  they  need  not
     (and cannot) be escaped using "<" and "&".

Note the parenthesis!

If I use CDATA in my RSS feed, however, I have to escape left an-
gle  brackets  for  correct  interpretation.  Don't know why. The
standard didn't change in this point since the first draft.
