  /**
   * <code>DocumentFragment</code> is a "lightweight" or "minimal"
   * <code>Document</code> object. It is very common to want to be able to
   * extract a portion of a document's tree or to create a new fragment of a
   * document. Imagine implementing a user command like cut or rearranging a
   * document by moving fragments around. It is desirable to have an object
   * which can hold such fragments and it is quite natural to use a Node for
   * this purpose. While it is true that a <code>Document</code> object could
   * fulfill this role, a <code>Document</code> object can potentially be a
   * heavyweight object, depending on the underlying implementation. What is
   * really needed for this is a very lightweight object.
   * <code>DocumentFragment</code> is such an object.
   * <p>Furthermore, various operations -- such as inserting nodes as children
   * of another <code>Node</code> -- may take <code>DocumentFragment</code>
   * objects as arguments; this results in all the child nodes of the
   * <code>DocumentFragment</code> being moved to the child list of this node.
   * <p>The children of a <code>DocumentFragment</code> node are zero or more
   * nodes representing the tops of any sub-trees defining the structure of
   * the document. <code>DocumentFragment</code> nodes do not need to be
   * well-formed XML documents (although they do need to follow the rules
   * imposed upon well-formed XML parsed entities, which can have multiple top
   * nodes). For example, a <code>DocumentFragment</code> might have only one
   * child and that child node could be a <code>Text</code> node. Such a
   * structure model represents neither an HTML document nor a well-formed XML
   * document.
   * <p>When a <code>DocumentFragment</code> is inserted into a
   * <code>Document</code> (or indeed any other <code>Node</code> that may
   * take children) the children of the <code>DocumentFragment</code> and not
   * the <code>DocumentFragment</code> itself are inserted into the
   * <code>Node</code>. This makes the <code>DocumentFragment</code> very
   * useful when the user wishes to create nodes that are siblings; the
   * <code>DocumentFragment</code> acts as the parent of these nodes so that
   * the user can use the standard methods from the <code>Node</code>
   * interface, such as <code>Node.insertBefore</code> and
   * <code>Node.appendChild</code>.
   * <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>.
