// Flags for diagnostic:
//
//   DIAG_TYPE - Allows one of:
//     NOTE      - Informational message.
//     WARNING   - Warning.
//     EXTENSION - Notification that an extension to the language is being used.
//     EXTWARN   - Warning for behaviour that is supported as an extension. This 
//                 differs from EXTENSION in that the warning is always emitted
//                 by default.
//     ERROR     - Error, compilation will stop after parsing completes.
