/**
* 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>CharacterData.data</code> attribute holds the text that is
* contained by the CDATA section. Note that this <em>may</em> 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>CDATASection</code> interface inherits from the
* <code>CharacterData</code> interface through the <code>Text</code>
* interface. Adjacent <code>CDATASection</code> nodes are not merged by use
* of the <code>normalize</code> method of the <code>Node</code> interface.
* <p> No lexical check is done on the content of a CDATA section and it is
* therefore possible to have the character sequence <code>"]]>"</code>
* in the content, which is illegal in a CDATA section per section 2.7 of [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>]. The
* presence of this character sequence must generate a fatal error during
* serialization or the cdata section must be splitted before the
* serialization (see also the parameter <code>"split-cdata-sections"</code>
* in the <code>DOMConfiguration</code> interface).
* <p ><b>Note:</b> Because no markup is recognized within a
* <code>CDATASection</code>, character numeric references cannot be used as
* an escape mechanism when serializing. Therefore, action needs to be taken
* when serializing a <code>CDATASection</code> with a character encoding
* where some of the contained characters cannot be represented. Failure to
* do so would not produce well-formed XML.
* <p ><b>Note:</b> 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/2004/REC-DOM-Level-3-Core-20040407'>Document acdk::lang::Object Model (DOM) Level 3 Core Specification</a>.
