* When a document is first made available to the DOM, there is only
* one Text object for each block of adjacent plain-text. Users (ie,
* applications) may create multiple adjacent Texts during editing --
* see {@link org.w3c.dom.Element#normalize} for discussion.

* Note that CDATASection is a subclass of Text. This is conceptually
* valid, since they're really just two different ways of quoting
* characters when they're written out as part of an XML stream.
