// Implementation notes:
//
// 1. If adding or changing any properties, please update the
//    following:
//
//    __ Update JDProperties.java (this source file).  NEW PROPERTIES
//       MUST BE ADDED TO THE END OF THE ARRAY (see @W2)
//
//    __ Add an entry to JDBCProperties.html.  Contact Information Development to
//       change this file.
//
//    __ Add entries to JDMRI.java.  The description entry should
//       match the first sentence in the description in
//       JDBCProperties.html.
//
//    __ Add getXXX/setXXX methods to AS400JDBCDataSource.java.
//
//    __ Add getXXX/setXXX methods to AS400JDBCManagedDataSource.java
//
//    __ Add a property to AS400JDBCDataSourceBeanInfo.java.
//
//    __ Update testcases JDDriverGetPropertyInfo.java,
//                        AS400JDBCConnectionPoolDataSourceBeanInfoTestcase.java,
//                        AS400JDBCDataSourceBeanInfoTestcase.java,
//                        JDConnectionCommit.java,
//
//    __ Test serialization
//
// 2. We only store the key to the descriptions.  We only
//    load the actual descriptions when the caller asks
//    for them.  This saves the descriptions from being
//    loaded in all cases.
