The \class{Text} interface represents text in the XML document. It

The \class{Text} interface represents text in the XML document. If
the parser and DOM implementation support the DOM's XML extension,
portions of the text enclosed in CDATA marked sections are stored in
\class{CDATASection} objects. These two interfaces are identical, but
provide different values for the \member{nodeType} attribute.
These interfaces extend the \class{Node} interface. They cannot have
child nodes.

\strong{Note:} The use of a \class{CDATASection} node does not
indicate that the node represents a complete CDATA marked section,
only that the content of the node was part of a CDATA section. A
single CDATA section may be represented by more than one node in the
document tree. There is no way to determine whether two adjacent
\class{CDATASection} nodes represent different CDATA marked sections.
