JQuery Validate multiple fields with one error

Question

How would I use the JQuery Validate plugin to have one error message for say 3 fields. For example 3 dob fields. By default I will get 3 error messages if all 3 fields are left blank. I only want one error linked to 3 fields. If any are blank the error comes up.

Similar to Chris's

$("form").validate({
    rules: {
        DayOfBirth: { required: true },
        MonthOfBirth: { required: true },
        YearOfBirth: { required: true }
    },
    groups: {
        DateofBirth: "DayOfBirth MonthOfBirth YearOfBirth"
    },
   errorPlacement: function(error, element) {
       if (element.attr("name") == "DayOfBirth" || element.attr("name") == "MonthOfBirth" || element.attr("name") == "YearOfBirth") 
        error.insertAfter("#YearOfBirth");
       else 
        error.insertAfter(element);
   }
});
