I guess the answer to "what is a rule engine" is there : What can Rules Engines accomplish?

But that's a too broad definition. In fact a "rule engine" should be totally dependant on your domain. The engine will provide settings (XML based or anything else suitable for the task) and then apply the rules.

So look for domain-specific engines and you'll certainly find something useful.
