Postfix (aka Reverse Polish Notation (RPN)) notation is used to describe mathmatical equations. It uses a stack where operands (either fixed values or ParameterInstances) are pushed onto the stack from first to last in the XML. As the operators are specified, each pops off operands as it evaluates them, and pushes the result back onto the stack. In this case postfix is used to avoid having to specify parenthesis. To convert from infix to postfix, use Dijkstra's "shunting yard" algorithm.
Java class for MathOperationType complex type.

    Gets the value of the valueOperandOrThisParameterOperandOrParameterInstanceRefOperand property.
    This accessor method returns a reference to the live list, not a snapshot. Therefore any modification you make to the returned list will be present inside the Jakarta XML Binding object. This is why there is not a set method for the valueOperandOrThisParameterOperandOrParameterInstanceRefOperand property.
    For example, to add a new item, do as follows:
    getValueOperandOrThisParameterOperandOrParameterInstanceRefOperand().add(newItem);
    
    Objects of the following type(s) are allowed in the list Double Object String ParameterInstanceRefType
