	// A set of predefined rules based on the desired purpose of the steering policy. Each
	// template utilizes Traffic Management's rules in a different order to produce the desired
	// results when answering DNS queries.
	//
	// **Example:** The `FAILOVER` template determines answers by filtering the policy's answers
	// using the `FILTER` rule first, then the following rules in succession: `HEALTH`, `PRIORITY`,
	// and `LIMIT`. This gives the domain dynamic failover capability.
	//
	// It is **strongly recommended** to use a template other than `CUSTOM` when creating
	// a steering policy.
	//
	// All templates require the rule order to begin with an unconditional `FILTER` rule that keeps
	// answers contingent upon `answer.isDisabled != true`, except for `CUSTOM`. A defined
	// `HEALTH` rule must follow the `FILTER` rule if the policy references a `healthCheckMonitorId`.
	// The last rule of a template must must be a `LIMIT` rule. For more information about templates
	// and code examples, see Traffic Management API Guide (https://docs.oracle.com/iaas/Content/TrafficManagement/Concepts/trafficmanagementapi.htm).
	// **Template Types**
	// * `FAILOVER` - Uses health check information on your endpoints to determine which DNS answers
	// to serve. If an endpoint fails a health check, the answer for that endpoint will be removed
	// from the list of available answers until the endpoint is detected as healthy.
	//
	// * `LOAD_BALANCE` - Distributes web traffic to specified endpoints based on defined weights.
	//
	// * `ROUTE_BY_GEO` - Answers DNS queries based on the query's geographic location. For a list of geographic
	// locations to route by, see Traffic Management Geographic Locations (https://docs.oracle.com/iaas/Content/TrafficManagement/Reference/trafficmanagementgeo.htm).
	//
	// * `ROUTE_BY_ASN` - Answers DNS queries based on the query's originating ASN.
	//
	// * `ROUTE_BY_IP` - Answers DNS queries based on the query's IP address.
	//
	// * `CUSTOM` - Allows a customized configuration of rules.
