061: * XML provides the CDATA markup to allow a region of text in which
062: * most of the XML delimiter recognition does not take place. This is
063: * intended to ease the task of quoting XML fragments and other
064: * programmatic information in a document's text without needing to
065: * escape these special characters. It's primarily a convenience feature
066: * for those who are hand-editing XML.
067: * <P>
068: * CDATASection is an Extended DOM feature, and is not used in HTML
069: * contexts.
070: * <P>
071: * Within the DOM, CDATASections are treated essentially as Text
072: * blocks. Their distinct type is retained in order to allow us to
073: * properly recreate the XML syntax when we write them out.
074: * <P>
075: * Reminder: CDATA IS NOT A COMPLETELY GENERAL SOLUTION; it can't
076: * quote its own end-of-block marking. If you need to write out a
077: * CDATA that contains the ]]> sequence, it's your responsibility to
078: * split that string over two successive CDATAs at that time.
079: * <P>
080: * CDATA does not participate in Element.normalize() processing.
081: *
082: * @version
