Add multiple validators to a Schema field #718

I'm not sure if there is already way to add more than one validator to a field.

I'm working on a project and I wanted to add multiple validators to a field, so for example:

Instead of having:
'username': [func, 'error msg']

I wanted something like:
'username': [func1, 'error msg'], [func2, 'error msg2']

I came up with this solution:

  User = new Schema({
    'username': {
      type: String,
      validate: [validator1, 'validator1 error'],
    'email': { 
      type: String,
      validate: [
          'func': validator1,
          'error': 'validator1 error'
          'func': validator2,
          'error': 'validator2 error'

I made some changes to the validate method to accept an object of validators:
I tested the changes and apparently is working

I wasn't sure how to name the properties of the validator object, so I just gave 'func' for the function to be called when validating and 'error' for the error message

Reading the documentation I saw that it's possible to add multiple validators calling explicity the validate function on the Schema

User.path('username').validate(function (v) {
  return false;
  }, 'my error type'); 
  User.path('username').validate(function (v) {
    return true;
  }, 'another error');

Shouldn't also be possible to add multiple validators when defining the schema?
