     * that the property will be a
     * SDODataTypes.DATE.

     * So this example uses a converter that transforms a string column 
     * into a date property and conversely, a date property back to a string for the
     * underlying column.
     * 
     * The converter returns 1957.09.27 if the column value is "Williams" 
     * and 1966.12.20 if the value is "Pavick"
     * 
     * On write, the converter returns "Pavick" if the property value is 
     * 1966.12.20 and "Williams" if the property value is 1957.09.27
