/**
* The <code>Text</code> interface inherits from <code>CharacterData</code>
* and represents the textual content (termed character data in XML) of an
* <code>Element</code> or <code>Attr</code>. If there is no markup inside
* an element's content, the text is contained in a single object
* implementing the <code>Text</code> interface that is the only child of
* the element. If there is markup, it is parsed into the information items
* (elements, comments, etc.) and <code>Text</code> nodes that form the list
* of children of the element.
* <p>When a document is first made available via the DOM, there is only one
* <code>Text</code> node for each block of text. Users may create adjacent
* <code>Text</code> 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
* <code>normalize()</code> method on <code>Node</code> merges any such
* adjacent <code>Text</code> objects into a single node for each block of
* text.
* <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
