/**
* The VSystemValueGroup class defines the representation of a
* system value group on a server for use in various models
* and panes in this package.
* You must explicitly call load() to load the information from
* the server.
*
* Most errors are reported as ErrorEvents rather than
* throwing exceptions. Users should listen for ErrorEvents
* in order to diagnose and recover from error conditions.
*
*
VSystemValueGroup objects generate the following events:
*
* - ErrorEvent
*
- PropertyChangeEvent
*
- VObjectEvent
*
- WorkingEvent
