/**
* 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 Node merges any such
* adjacent Text objects into a single node for each block of
* text.
*
