Represents CDATA sections of the XML document.
CDATA sections are used to escape blocks of text containing characters that would otherwise be regarded as markup.
By default, CDATA sections are parsed into the normal TEXT nodes.
However, when #CDATA pseudo-elements are enabled, the CDATA sections
will be recognized separately and produce #CDATA pseudo-elements.
Value:
#TEXT and #CDATA types.

<![CDATA[
write '<' instead of '<' here
]]>
#CDATA pseudo-element with the value:
"write '<' instead of '<' here"
