This is the solution I used (thanks to @shakinfree for the hint) :

var mongoose = require('mongoose'),
Schema = mongoose.Schema;

// schema definition
var ASchema = new Schema({
  dateSchema : {
                type:{
                    startDate:{type:Date, required: true}, 
                    endDate:{type:Date, required: true}
                }, 
                required: true, 
                validate: [dateValidator, 'Start Date must be less than End Date']
            }
});

// function that validate the startDate and endDate
function dateValidator (value) {
    return value.startDate <= value.endDate;
}

module.exports = mongoose.model('A', ASchema);
