Copyright (C) 2000 Norman Walsh.

This class provides a Saxon 6.* implementation of an emitter that manufactures a cloned result tree fragment.

The purpose of this emitter is to provide something for CalloutEmitter and NumberLinesEmitter to extend. This emitter simply copies all input to a new result tree fragment.
