No. It's simply not allowed and the standard describes no way how to 
deal with such a situation, though it declares the nesting of CDATA 
sections as forbidden.

MSDN has only a tip for script developers: when you need "]]>" you may 
often write "] ]>".

I think we can ignore the situation and add to the function specs that 
$useCDATA forbids the character sequences <![CDATA[ and ]]>.
