/**

 * CDATA sections are used to escape blocks of text containing characters that

 * would otherwise be regarded as markup. The only delimiter that is

 * recognized in a CDATA section is the "]]>" string that ends the CDATA

 * section. CDATA sections cannot be nested. Their primary purpose is for

 * including material such as XML fragments, without needing to escape all

 * the delimiters.

 * <p>The <code>data</code> attribute of the <code>DOMText</code> node holds

 * the text that is contained by the CDATA section. Note that this may

 * contain characters that need to be escaped outside of CDATA sections and

 * that, depending on the character encoding ("charset") chosen for

 * serialization, it may be impossible to write out some characters as part

 * of a CDATA section.

 * <p>The <code>DOMCDATASection</code> interface inherits from the

 * <code>DOMCharacterData</code> interface through the <code>DOMText</code>

 * interface. Adjacent <code>DOMCDATASection</code> nodes are not merged by use

 * of the <code>normalize</code> method of the <code>DOMNode</code> interface.

 * Because no markup is recognized within a <code>DOMCDATASection</code>,

 * character numeric references cannot be used as an escape mechanism when

 * serializing. Therefore, action needs to be taken when serializing a

 * <code>DOMCDATASection</code> with a character encoding where some of the

 * contained characters cannot be represented. Failure to do so would not

 * produce well-formed XML.One potential solution in the serialization

 * process is to end the CDATA section before the character, output the

 * character using a character reference or entity reference, and open a new

 * CDATA section for any further characters in the text node. Note, however,

 * that some code conversion libraries at the time of writing do not return

 * an error or exception when a character is missing from the encoding,

 * making the task of ensuring that data is not corrupted on serialization

 * more difficult.

 * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
