	//
	//    * ParameterReference entities are Ref intrinsic functions that get template
	//    parameter values, such as { "Ref" : "MyPasswordParameter" }.
	//

	//    resource attribute values, such as { "Fn::GetAtt" : [ "MyEC2InstanceResource",
	//    "PublicDnsName" ] }.
	//
	//    * DirectModification entities are changes that are made directly to the
	//    template.
	//
	//    * Automatic entities are AWS::CloudFormation::Stack resource types, which
	//    are also known as nested stacks. If you made no changes to the AWS::CloudFormation::Stack
	//    resource, AWS CloudFormation sets the ChangeSource to Automatic because
	//    the nested stack's template might have changed. Changes to a nested stack's

	// InstanceType property of an EC2 instance, AWS CloudFormation knows that this
	// property value will change, and its value, so this is a Static evaluation.
	//
	// For Dynamic evaluations, cannot determine the target value because it depends
	// on the result of an intrinsic function, such as a Ref or Fn::GetAtt intrinsic
	// function, when the stack is updated. For example, if your template includes
	// a reference to a resource that is conditionally recreated, the value of the
