	/// The CharacterData interface extends Node with a set of attributes and methods
	/// for accessing character data in the DOM. For clarity this set is defined
	/// here rather than on each object that uses these attributes and methods.
	/// No DOM objects correspond directly to CharacterData, though Text and others
	/// do inherit the interface from it. All offsets in this interface start from 0.
	/// 
	/// Text strings in the DOM are represented in either UTF-8 (if XML_UNICODE_WCHAR_T is
	/// not defined) or in UTF-16 (if XML_UNICODE_WCHAR_T is defined).
	/// Indexing on character data is done in XMLChar units.
