/// In the DOM, child nodes are usually appended to a parent
/// node using the appendChild() method. For nodes containing
/// more than a few children, this method can be quite slow,
/// due to the way it's implemented, and because of the
/// requirements of the DOM specification.
///
/// While the NodeAppender is being used on an Element, no
/// children-modifying methods of that Element must be used.

/// This class is not part of the DOM specification.

/// the parent node specified in the constructor.

/// NewChild can be a DocumentFragment. In this case, all children
/// of the fragment become children of the parent element.
