| /** |
| * The <code>Text</code> interface inherits from <code>CharacterData</code> |
| * and represents the textual content (termed <a href='http://www.w3.org/TR/2004/REC-xml-20040204#syntax'>character data</a> 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>Node.normalize()</code> method merges any such adjacent |
| * <code>Text</code> objects into a single node for each block of text. |
| * <p> No lexical check is done on the content of a <code>Text</code> node |
| * and, depending on its position in the document, some characters must be |
| * escaped during serialization using character references; e.g. the |
| * characters "<&" if the textual content is part of an element or of |
| * an attribute, the character sequence "]]>" when part of an element, |
| * the quotation mark character " or the apostrophe character ' when part of |
| * an attribute. |
| * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>Document Object Model (DOM) Level 3 Core Specification</a>. |
