Can I create a DocumentArray without the sub-document _id?

When I have such a Schema:

var StudentSchema = new Schema({
  _id : Schema.Types.ObjectId,
  clazz : { type: String, ref: 'Class' },
  number : { type: Number },
  name : [{
    lang: String,
    full : { type: String, trim: true }
  }]
});

Each name would be automatically added an _id. I would not use if for any operation my use case, how can I specify in the Schema to drop it?

new Schema({..}, { _id: false })

Roger that.

I started out without defining a Schema for the names and that’s why I hit the wall.
