- /**
- * OMDocumentFragment is a "lightweight" or "minimal"
- * DOMDocument 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 DOMNode for
- * this purpose. While it is true that a <code>DOMDocument</code> object could
- * fulfil this role, a <code>DOMDocument</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>DOMDocumentFragment</code> is such an object.
- * <p>Furthermore, various operations -- such as inserting nodes as children
- * of another <code>DOMNode</code> -- may take <code>DOMDocumentFragment</code>
- * objects as arguments; this results in all the child nodes of the
- * <code>DOMDocumentFragment</code> being moved to the child list of this node.
- * <p>The children of a <code>DOMDocumentFragment</code> node are zero or more
- * nodes representing the tops of any sub-trees defining the structure of the
- * document. <code>DOMDocumentFragment</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>DOMDocumentFragment</code> might have only one
- * child and that child node could be a <code>DOMText</code> node. Such a
- * structure model represents neither an HTML document nor a well-formed XML
- * document.
- * <p>When a <code>DOMDocumentFragment</code> is inserted into a
- * <code>DOMDocument</code> (or indeed any other <code>DOMNode</code> that may take
- * children) the children of the <code>DOMDocumentFragment</code> and not the
- * <code>DOMDocumentFragment</code> itself are inserted into the
- * <code>DOMNode</code>. This makes the <code>DOMDocumentFragment</code> very
- * useful when the user wishes to create nodes that are siblings; the
- * <code>DOMDocumentFragment</code> acts as the parent of these nodes so that the
- * user can use the standard methods from the <code>DOMNode</code> interface,
- * such as <code>insertBefore()</code> and <code>appendChild()</code>.
