I think the experience with disable-output-escaping shows that any facility
that requires out-of-band communication between the transformer and the
serializer is architecturally very bad news.

Mind you, I've never found cdata-section-elements very useful. It only
serves to encourage people in the mistaken belief that CDATA section
boundaries are information-bearing.
