[rules-users] [Drools Activation-group] / how to set many activation groups

[Wolfgang Laun]

All rule attributes are (more or less) just ad-hoc shortcuts for certain
scenarios which can, with little effort, be implemented using the
elementary techniques of inference, truth maintenance, fact manipulation
etc.

In fact, not letting rule attributes befuddle your mind will enable
you to design a clean logic. Finally, you proceed to implementation,
and then - only then - it is time to think about applying those
shortcuts.
