A CDATA section marks text as "just text".

Element-like syntax will be ignored.

Syntax:

[18]    CDSect    ::=    CDStart CData CDEnd
[19]    CDStart   ::=    '<![CDATA['
[20]    CData     ::=    (Char* - (Char* ']]>' Char*))
[21]    CDEnd     ::=    ']]>'

That is, a CDATA section contains text except that ']]>' is not allowed in the content.

Example:

<![CDATA[<greeting>Hello, world!</greeting>]]> 

This generates the text '<greeting>Hello, world!</greeting>' and not the element 'greeting'.
