This is a _very_ simple example of a JSON schema. There is only one property.

| :------------------ | ---------- | -------------- | ------------ | :---------------- | --------------------- | ------------------- | ------------------------------------------------------------------------------------ |
| Can be instantiated | No         | Unknown status | No           | Forbidden         | Allowed               | none                | [simple.schema.json](../generated-schemas/simple.schema.json "open original schema") |
