 * DocumentFragment is a "lightweight" or "minimal" Document
 * 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
 * Document object could fulfil this role, a Document object can
 * potentially be a heavyweight object, depending on the underlying
 * implementation... and in DOM Level 1, nodes aren't allowed to cross
 * Document boundaries anyway. What is really needed for this is a
 * very lightweight object.  DocumentFragment is such an object.
 * <P>
 * Furthermore, various operations -- such as inserting nodes as
 * children of another Node -- may take DocumentFragment objects as
 * arguments; this results in all the child nodes of the
 * DocumentFragment being moved to the child list of this node.
 * <P>
 * The children of a DocumentFragment node are zero or more nodes
 * representing the tops of any sub-trees defining the structure of
 * the document.  DocumentFragment 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 DocumentFragment might have only one child
 * and that child node could be a Text node. Such a structure model
 * represents neither an HTML document nor a well-formed XML document.
 * <P>
 * When a DocumentFragment is inserted into a Document (or indeed any
 * other Node that may take children) the children of the
 * DocumentFragment and not the DocumentFragment itself are inserted
 * into the Node. This makes the DocumentFragment very useful when the
 * user wishes to create nodes that are siblings; the DocumentFragment
 * acts as the parent of these nodes so that the user can use the
 * standard methods from the Node interface, such as insertBefore()
 * and appendChild().
