* CharacterData is an abstract Node that can carry character data as its
* Value. It provides shared behavior for Text, CData, and
* possibly other node types. All offsets are 0-based.
* <p>
* Since ProcessingInstructionImpl inherits from this class to reuse the
* setNodeValue method, this class isn't declared as implementing the interface
* CharacterData. This is done by relevant subclasses (TexImpl, CommentImpl).
* <p>
* This class doesn't directly support mutation events, however, it notifies
* the document when mutations are performed so that the document class do so.
