 * Description:  base class for derived classes to contain all the
 *               legal options in the LIKE clause of a DDL statement.
 *
 *               Note that the derived classes do not represent parse
 *               nodes.  Several kinds of parse nodes contain these
 *               derived classes.
 *
 *               
 * Created:      6/6/95
 * Language:     C++
