Markup's part of the data. Particularly in chrismorgan's example, where it's semantic content. As for CDATA, I think you're right that it'd work in this case (assuming that client apps cope with it there, but if the Atom equivalent works then presumably it should). I suspect that what we're looking at here is software which is poorly generating its RSS. Probably Wordpress, since I'm at least fairly confident that it doesn't put CDATA in its item titles regardless of their content.
