/**
 * <code>DocumentFragment is a "lightweight" or "minimal"
 * <code>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 <code>Document object could
 * fulfill this role, a <code>Document 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 is such an object.
 * <p>Furthermore, various operations -- such as inserting nodes as children
 * of another <code>Node -- may take DocumentFragment
 * objects as arguments; this results in all the child nodes of the
 * <code>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. <code>DocumentFragment 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 might have only one
 * child and that child node could be a <code>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
 * <code>Document (or indeed any other Node that may
 * take children) the children of the <code>DocumentFragment and not
 * the <code>DocumentFragment itself are inserted into the
 * <code>Node. This makes the DocumentFragment very
 * useful when the user wishes to create nodes that are siblings; the
 * <code>DocumentFragment acts as the parent of these nodes so that
 * the user can use the standard methods from the <code>Node
 * interface, such as <code>Node.insertBefore and
 * <code>Node.appendChild.
 * <p>See also the Document Object Model (DOM) Level 3 Core Specification.
