--
-- Lists the resource record sets in a specified hosted zone.
--
--
-- @ListResourceRecordSets@ returns up to 100 resource record sets at a time in ASCII order, beginning at a position specified by the @name@ and @type@ elements. The action sorts results first by DNS name with the labels reversed, for example:
--
-- @com.example.www.@
--
-- Note the trailing dot, which can change the sort order in some circumstances.
--
-- When multiple records have the same DNS name, the action sorts results by the record type.
--
-- You can use the name and type elements to adjust the beginning position of the list of resource record sets returned:
--
--     * If you do not specify Name or Type    * The results begin with the first resource record set that the hosted zone contains.
--
--     * If you specify Name but not Type    * The results begin with the first resource record set in the list whose name is greater than or equal to @Name@ .
--
--     * If you specify Type but not Name    * Amazon Route 53 returns the @InvalidInput@ error.
--
--     * If you specify both Name and Type    * The results begin with the first resource record set in the list whose name is greater than or equal to @Name@ , and whose type is greater than or equal to @Type@ .
--
--
--
-- This action returns the most current version of the records. This includes records that are @PENDING@ , and that are not yet available on all Amazon Route 53 DNS servers.
--
-- To ensure that you get an accurate listing of the resource record sets for a hosted zone at a point in time, do not submit a @ChangeResourceRecordSets@ request while you're paging through the results of a @ListResourceRecordSets@ request. If you do, some pages may display results without the latest changes while other pages display results with the latest changes.
--
--
-- This operation returns paginated results.

-- * 'lrrsStartRecordName' - The first name in the lexicographic ordering of resource record sets that you want to list.
--

Valid values for basic resource record sets: @A@ | @AAAA@ | @CAA@ | @CNAME@ | @MX@ | @NAPTR@ | @NS@ | @PTR@ | @SOA@ | @SPF@ | @SRV@ | @TXT@  Values for weighted, latency, geo, and failover resource record sets: @A@ | @AAAA@ | @CAA@ | @CNAME@ | @MX@ | @NAPTR@ | @PTR@ | @SPF@ | @SRV@ | @TXT@  Values for alias resource record sets:      * __CloudFront distribution__ : A or AAAA     * __Elastic Beanstalk environment that has a regionalized subdomain__ : A     * __ELB load balancer__ : A | AAAA     * __Amazon S3 bucket__ : A     * __Another resource record set in this hosted zone:__ The type of the resource record set that the alias references. Constraint: Specifying @type@ without specifying @name@ returns an @InvalidInput@ error.
--
-- * 'lrrsStartRecordIdentifier' - /Weighted resource record sets only:/ If results were truncated for a given DNS name and type, specify the value of @NextRecordIdentifier@ from the previous response to get the next resource record set that has the current DNS name and type.
--
-- * 'lrrsMaxItems' - (Optional) The maximum number of resource records sets to include in the response body for this request. If the response includes more than @maxitems@ resource record sets, the value of the @IsTruncated@ element in the response is @true@ , and the values of the @NextRecordName@ and @NextRecordType@ elements in the response identify the first resource record set in the next group of @maxitems@ resource record sets.
