 Each tool will have its own way to provide for validation. Bindings or configurations to link documents to schemas can be maintained either inside or outside the documents themselves; many tools offer several ways to do this.

Similarly, you can use the [`ajv-cli`](https://github.com/ajv-validator/ajv-cli) for JSON.
