<p>
Routing controls that can only be set or unset if the specified RuleConfig evaluates to true for the specified
GatingControls. For example, say you have three gating controls, one for each of three Amazon Web Services
Regions. Now you specify ATLEAST 2 as your RuleConfig. With these settings, you can only change (set or unset)
the routing controls that you have specified as TargetControls if that rule evaluates to true.

In other words, your ability to change the routing controls that you have specified as TargetControls is gated by
the rule that you set for the routing controls in GatingControls.
