How do you make your AWS ELB internal in a AWS Cloudformation template?

I am templating an EB app and several environments. I want to ensure that the ELB is set to be internal, but cant find the reference in the Cloudformation documentation.

You can configure an internal Elastic Load Balancer within an Elastic Beanstalk application by setting the ELBScheme property in the EB's aws:ec2:vpc namespace:

Specify internal if you want to create an internal load balancer in your VPC so that your Elastic Beanstalk application cannot be accessed from outside your VPC.

To configure this within a CloudFormation template, add the option to the OptionSettings property of your AWS::ElasticBeanstalk::Environment resource:

Type: AWS::ElasticBeanstalk::Environment
Properties: 
  ApplicationName: !Ref AppName
  SolutionStackName: !Ref SolutionStackName
  OptionSettings: 
    - 
      Namespace: "aws:ec2:vpc"
      OptionName: ELBScheme
      Value: internal

It's the "Scheme" parameter: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-elb.html#cfn-ec2-elb-scheme

Accepts either 'internal' or 'internet-facing' as a string.
