What Is a JSON Document Type?
JSON document types are based on JSON schemas and provide support for JSON schema features such as validation. Every instance of a JSON document type includes a root document. Within this root document, an instance can include:
Fields that correspond to JSON schema fields and contain validation properties.
Other JSON document types that correspond to the JSON objects in the given JSON schema.
Note:
The ref keyword in a JSON schema will generate another JSON document type and include that document type in the top-level document type.
The following samples show a JSON schema and the JSON document type created from that schema.

"type": "object",
"properties": {
"streetAddress": {

}
}
},
