	/// The Text interface inherits from CharacterData and represents the textual
	/// content (termed character data in XML) of an Element or Attr. If there is
	/// no markup inside an element's content, the text is contained in a single
	/// object implementing the Text interface that is the only child of the element.
	/// If there is markup, it is parsed into the information items (elements, comments,
	/// etc.) and Text nodes that form the list of children of the element.
	/// 
	/// When a document is first made available via the DOM, there is only one Text
	/// node for each block of text. Users may create adjacent Text nodes that represent
	/// the contents of a given element without any intervening markup, but should
	/// be aware that there is no way to represent the separations between these
	/// nodes in XML or HTML, so they will not (in general) persist between DOM
	/// editing sessions. The normalize() method on Element merges any such adjacent
	/// Text objects into a single node for each block of text.

		/// point. When the offset is equal to the length of this node, the new node
