| * The <code>Text</code> interface 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 a |
| * list of elements 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, so they |
| * will not (in general) persist between DOM editing sessions. The |
| * <code>normalize()</code> method on <code>Element</code> merges any such |
| * adjacent <code>Text</code> objects into a single node for each block of |
| * text; this is recommended before employing operations that depend on a |
| * particular document structure, such as navigation with |
