You can declare that an element's content be ***PCDATA*** (i.e., parsed
character data). An attribute's value can be CDATA, not an element.
A CDATA ***section*** is not declared, you just put in the content of an
element and the parser will understand what you mean.
You still can't use characters that are illegal in XML, though. Base64
encoding is commonly used for this.
