CDATASection

The CDATASection interface represents a CDATA section that can be used within XML to include extended portions of unescaped text. The symbols < and & don’t need escaping as they normally do when inside a CDATA section.

In XML, a CDATA section looks like:

<![CDATA[ ... ]]>

For example:

<foo>Here is a CDATA section: <![CDATA[ < > & ]]> with all kinds of unescaped text.</foo>

The only sequence which is not allowed within a CDATA section is the closing sequence of a CDATA section itself, ]]>:

<![CDATA[ ]]> will cause an error ]]>

Note that CDATA sections should not be used within HTML; they only work in XML.
