          :type domain_name: str
          :param domain_name: The name of the domain. This should be a
              fully-specified domain, and should end with a final period
              as the last label indication.  If you omit the final period,
              Amazon Route 53 assumes the domain is relative to the root.
              This is the name you have registered with your DNS registrar.
              It is also the name you will delegate from your registrar to
              the Amazon Route 53 delegation servers returned in
              response to this request.A list of strings with the image
              IDs wanted.
  
          :type caller_ref: str
          :param caller_ref: A unique string that identifies the request
              and that allows failed CreateHostedZone requests to be retried
              without the risk of executing the operation twice.  If you don't
              provide a value for this, boto will generate a Type 4 UUID and
              use that.
  
          :type comment: str
          :param comment: Any comments you want to include about the hosted      
              zone.
