What you're describing though is a configuration variability which would be expressable by a static tagging regime - still simple. If your configuration is getting more complex then that though, again, it's not really configuration anymore - it's a management application which needs to be developed and treated like that. And why it's that complicated should be re-evaluated - i.e. how come this is "configuration" and not something the application detects for itself? Why is it being surfaced to the user (operator) at all?
