Create a system action in ODC where a message can be logged to the error log.
LogMessage will log a message to the general log. O11 has the AsynchronousLogging extension that has a LogError action, but ODC does not.
In ODC, an application can log to the error log by throwing an exception.
However, there are occasions when the application needs to continue processing. In this scenario it would be useful to log a message to the error log and continue operation.
