JSON Schema implementation error

inputEx.JsonSchema.Builder doesn't handle a json-schema without a top-level type property. It builds a form with a single textbox instead.

Adding a type property allows the form to generate properly, but the "type" property is optional according to the JSON-schema spec.

The following schema exibits the problem when used with JsonSchema.Builder.

{
	"id": "Address", 
	"description": "Generic Address", 
	"properties": {
		"address1": {
			"type": "string", 
			"title": "Address"
		}, 
		"address2": {
			"type": "string", 
			"optional": true, 
			"title": " "
		}, 
		"city": {
			"type": "string", 
			"title": "City"
		}, 
		"state": {
			"type": "string", 
			"title": "State", 
			"minLength": 2, 
			"maxLength": 2
		}, 
		"zip": {
			"type": "string", 
			"title": "Zip Code"
		}
	}
}
