+//  Use ChangeResourceRecordsSetsRequest to perform the following actions:
+//
+//    CREATE:Creates a resource record set that has the specified values.
+//
+//    DELETE: Deletes an existing resource record set that has the specified
+// values for Name, Type, Set Identifier (for code latency, weighted, geolocation,
+// and failover resource record sets), and TTL (except alias resource record
+// sets, for which the TTL is determined by the AWS resource you're routing
+// queries to).
+//
+//    UPSERT: If a resource record set does not already exist, AWS creates
+// it. If a resource set does exist, Amazon Route 53 updates it with the values
+// in the request. Amazon Route 53 can update an existing resource record set
+// only when all of the following values match: Name, Type, and Set Identifier
+// (for weighted, latency, geolocation, and failover resource record sets).
+//
+//   In response to a ChangeResourceRecordSets request, the DNS data is changed
+// on all Amazon Route 53 DNS servers. Initially, the status of a change is
+// PENDING, meaning the change has not yet propagated to all the authoritative
 // Amazon Route 53 DNS servers. When the change is propagated to all hosts,
 // the change returns a status of INSYNC.
 //
+// After sending a change request, confirm your change has propagated to all
+// Amazon Route 53 DNS servers. Changes generally propagate to all Amazon Route
+// 53 name servers in a few minutes. In rare circumstances, propagation can
+// take up to 30 minutes. For more information, see GetChange.
+//
 // Note the following limitations on a ChangeResourceRecordSets request:
 //
-//  A request cannot contain more than 100 Change elements.  A request cannot
-// contain more than 1000 ResourceRecord elements. The sum of the number of
-// characters (including spaces) in all Value elements in a request cannot exceed
-// 32,000 characters.

+//    A request cannot contain more than 1000 ResourceRecord elements.
+//
+//   The sum of the number of characters (including spaces) in all Value elements
+// in a request cannot exceed 32,000 characters.
+//
+//    If the value of the Action element in a ChangeResourceRecordSets request
+// is UPSERT and the resource record set already exists, Amazon Route 53 automatically
+// performs a DELETE request and a CREATE request. When Amazon Route 53 calculates
+// the number of characters in the Value elements of a change batch request,
+// it adds the number of characters in the Value element of the resource record
+// set being deleted and the number of characters in the Value element of the
+// resource record set being created.

+//    The same resource cannot be deleted more than once in a single batch.

+	// latency, geolocation, or failover resource record set, and you specify health
+	// check IDs for all of the resource record sets. If the health check for one

+	//
+	//   You set EvaluateTargetHealth to true for the resource record sets in an
+	// alias, weighted alias, latency alias, geolocation alias, or failover alias
+	// resource record set, and you specify health check IDs for all of the resource
+	// record sets that are referenced by the alias resource record sets.
+	//
+	//    Amazon Route 53 doesn't check the health of the endpoint specified in
+	// the resource record set, for example, the endpoint specified by the IP address
+	// in the Value element. When you add a HealthCheckId element to a resource
+	// record set, Amazon Route 53 checks the health of the endpoint that you specified
+	// in the health check.
+	//
+	//  For geolocation resource record sets, if an endpoint is unhealthy, Amazon
+	// Route 53 looks for a resource record set for the larger, associated geographic
+	// region. For example, suppose you have resource record sets for a state in
+	// the United States, for the United States, for North America, and for all
+	// locations. If the endpoint for the state resource record set is unhealthy,
+	// Amazon Route 53 checks the resource record sets for the United States, for
+	// North America, and for all locations (a resource record set for which the
+	// value of CountryCode is *), in that order, until it finds a resource record
+	// set for which the endpoint is healthy.
+	//
+	// If your health checks specify the endpoint only by domain name, we recommend
+	// that you create a separate health check for each endpoint. For example, create
+	// a health check for each HTTP server that is serving content for www.example.com.
+	// For the value of FullyQualifiedDomainName, specify the domain name of the
+	// server (such as us-east-1-www.example.com), not the name of the resource
+	// record sets (example.com).

+	//   If you specify a value of 80 for Port and HTTP or HTTP_STR_MATCH for Type,
+	// Amazon Route 53 passes the value of FullyQualifiedDomainName to the endpoint
+	// in the Host header.
+	//
+	//   If you specify a value of 443 for Port and HTTPS or HTTPS_STR_MATCH for

+	//
+	//   If you specify another value for Port and any value except TCP for Type,
+	// Amazon Route 53 passes  FullyQualifiedDomainName:Port  to the endpoint in
+	// the Host header.
+	//
+	//   If you don't specify a value for FullyQualifiedDomainName, Amazon Route
+	// 53 substitutes the value of IPAddress in the Host header in each of the above
+	// cases.
+	//
+	//  If you don't specify IPAddress:
+	//
+	// If you don't specify a value for IPAddress, Amazon Route 53 sends a DNS
+	// request to the domain that you specify in FullyQualifiedDomainName at the
+	// interval you specify in RequestInterval. Using an IP address that DNS returns,
+	// Amazon Route 53 then checks the health of the endpoint.
+	//
+	// If you want to check the health of weighted, latency, or failover resource
+	// record sets and you choose to specify the endpoint only by FullyQualifiedDomainName,
+	// we recommend that you create a separate health check for each endpoint. For
+	// example, create a health check for each HTTP server that is serving content

+	// of the resource record sets (www.example.com).
+	//
+	//  In this configuration, if the value of FullyQualifiedDomainName matches
+	// the name of the resource record sets and you then associate the health check
+	// with those resource record sets, health check results will be unpredictable.
+	//
+	//  In addition, if the value of Type is HTTP, HTTPS, HTTP_STR_MATCH, or HTTPS_STR_MATCH,
+	// Amazon Route 53 passes the value of FullyQualifiedDomainName in the Host
