| /** |
| * <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 |
| * fulfil 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>insertBefore()</code> and <code>appendChild()</code>. |
