    Description copied from interface: DataSet
    
    Create a new DataSet by filtering this DataSet's DataPoints matching the specified values for some identifiers.
    
    Parameters:
    
    keyValues - A Map containing values for some of this DataSet ComponentRole.Identifiers. If the map is empty, the result is this DataSet.
    
    Returns:
    
    A new DataSet of matching DataPoints, eventually empty.
