You could try nesting your date stamps in a parent object and then validate the parent. For example something like:

//create a simple object defining your dates
var dateStampSchema = {
  startDate: {type:Date},
  endDate: {type:Date}
};

//validation function
function checkDates(value) {
   return value.endDate < value.startDate; 
}

//now pass in the dateStampSchema object as the type for a schema field
var schema = new Schema({
   dateInfo: {type:dateStampSchema, validate:checkDates}
});
