# Complex References Schema

```
https://example.com/schemas/complex
```

This is an example schema that uses types defined in other schemas.

| [Abstract](../abstract.md) | Extensible | [Status](../status.md) | Identifiable | Custom Properties | Additional Properties | Defined In                                 |
| -------------------------- | ---------- | ---------------------- | ------------ | ----------------- | --------------------- | ------------------------------------------ |
| Can be instantiated        | No         | Experimental           | No           | Forbidden         | Permitted             | [complex.schema.json](complex.schema.json) |
