Ok, now I see what you are talking about.  You mean something
like:

CDATA cdata = new CDATA( "Stuff with a <![CDATA[Hello!]]> in it" );

Fortunately, this is disallowed by the Xml 1.0 Specification (S 2.7),
so it does not have to be dealt with.  However, to help the
application writer, you may want to do a:

if ( value.indexOf( "]]>" ) != -1 ) {
	Error...
}

in the CDATA constructor...
