Ah, but that explains it all: the CDATA signals to the parser that the 
following characters (up to ']]>') are to be treated as _literals_.

Which is correct: the '&' character in a literal "&qout;" has to be
escaped.  This is (one of) the reason(s) why having kind-of-escaped HTML
in an XML feed is really a bad idea [see for example:

CDATA is an unfortunate leftover from SGML where it served as a
convenience for authors who entered text manually.

Yes, it does (exactly as i feared :). As a possible workaround 
have a look at the cdata-section-elements attribute of the xslt:output
