The bottom line is that CDATA marked sections look like markup, but they're not. They are lexical cruft, having nothing to do with information as modeled in an XML system. They express nothing in XML that couldn't be expressed otherwise. They could have been left out of XML altogether and the semantics of XML as an information modeling and processing technology would be the same. But because they're there, and because they look like markup, and because they do mean something to a parser, they offer potentials for headaches. When used properly, as a merely syntactic alternative to escaping markup characters, they're a harmless convenience. When they invade processing semantics, they're an accident waiting to happen.
