Retired Workgroups
Share |

Once the solution and any supporting specifications are stable, maintenance workgroups are formally retired.  They no longer meet, and oversight of any specifications is transferred to the Forum. The workgroup can still be re-chartered if future needs arise. Minor maintenance issues may be handled by ad hoc committees appointed by the Forum chairs, or the workgroup can be reactivated as a maintenance workgroup for larger issues.
