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