This stackoverflow solutions does not work with json-gate: http://stackoverflow.com/questions/9029524/json-schema-specify-field-is-required-based-on-value-of-another-field

var schema = {
    "type": [
        {
            "title": "New Zealand (no postcode)",
            "type": "object",
            "properties": {
                "country": {"enum": ["NZ", "NZL", "NEW ZEALAND"]},
            }
        },
        {
            "title": "Other countries (require postcode)",
            "type": "object",
            "properties": {
                "country": {"enum": ["FR"]},
                "postcode": {"required": true}
            }
        },
    ],
    "properties": {
        "country": {
            "type" : "string",
            "default" : "AUS"
        },
        "postcode": {
            "type" : "string"
        }
    }
};

var instance1 = {
  country: "NZ"
};

var instance2 = {
  country: "FR",
  postcode: "42320"
};

var badInstance = {
  country: "FR"
};

var jsonschema = require('json-schema');
console.log(jsonschema.validate(instance1, schema));
console.log(jsonschema.validate(instance2, schema));
console.log(jsonschema.validate(badInstance, schema));

var schema = require('json-gate').createSchema(schema);
schema.validate(instance1);
schema.validate(instance2);
schema.validate(badInstance);

The output is:

{ valid: true, errors: [] }
{ valid: true, errors: [] }
{ valid: false,
  errors:
   [ { property: 'undefined.postcode',
       message: 'is missing and it is required' } ] }
