The Text interface represents the textual content of Element or Attr.  If an element has no markup within its content, it has a single child implementing Text that contains the element's text.  However, if the element contains markup, it is parsed into information items and Text nodes that form its children.

New documents have a single Text node for each block of text. Over time, more Text nodes may be created as the document's content changes.  The Node.normalize() method merges adjacent Text objects back into a single node for each block of text.
