All the other entries in this group consist of the following attributes that are needed
to describe a diagnostic event generated by one of the software subsystems.
The status of a diagnostic event is indicated by an ASCII string, which can have
one of the following values:
• "Initializing"
• "Major error"
• "Minor error"
• "Not ready"
• "Ready"
• "Last wish"
• "Shutdown"
• "No status"
The error code is assigned by the application when the status changes and precisely
describes the cause of the error.
