/**
* 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.
* The DOMString attribute of the Text 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.
*
The CDATASection interface inherits from the
* CharacterData interface through the Text
* interface. Adjacent CDATASection nodes are not merged by use
* of the normalize method of the Node interface.
* Because no markup is recognized within a CDATASection,
* character numeric references cannot be used as an escape mechanism when
* serializing. Therefore, action needs to be taken when serializing a
* CDATASection 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.
