	//

	// * If you are signed in to a delegated

	// The unique identifier for this stack set operation. The operation ID also

	// stack set operation only once, even if you retry the request multiple times. You
	// might retry stack set operation requests to ensure that CloudFormation
	// successfully received them. If you don't specify an operation ID, the SDK

	// A list of stack set parameters whose values you want to override in the selected
	// stack instances. Any overridden parameter values will be applied to all stack
	// instances in the specified accounts and Regions. When specifying parameters and
	// their values, be aware of how CloudFormation sets parameter values during stack
	// instance operations:
	//
	// * To override the current value for a parameter, include
	// the parameter and specify its value.
	//
	// * To leave an overridden parameter set to
	// its present value, include the parameter and specify UsePreviousValue as true.
	// (You cannot specify both a value and set UsePreviousValue to true.)
	//
	// * To set an
	// overridden parameter back to the value specified in the stack set, specify a
	// parameter list but do not include the parameter in the list.
	//
	// * To leave all
	// parameters set to their present values, do not specify this property at
	// all.
	//
	// During stack set updates, any parameter values overridden for a stack
	// instance are not updated, but retain their overridden value. You can only
	// override the parameter values that are specified in the stack set; to add or
	// delete a parameter itself, use UpdateStackSet
	// (https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html)
	// to update the stack set template.
