The CDATASection Interface
The CDATASection interface, shown in Example 11.11, is a subinterface of Text that specifically represents CDATA sections. It has no unique methods of its own, but when a CDATASection is serialized into a file, the text of the node may be wrapped inside CDATA section markers. As a result, characters such as ampersand and the less-than sign do not need to be escaped as & and <.
