 ### JSON Schema validation
 
-As well as dynamically controlling *access* to the various edit tools as described above, it's possible to do full [JSON Schema](https://json-schema.org/) validation by creating an [Update Function](#update-functions) that passes the data to a 3rd-party schema validation library (e.g. [Ajv](https://ajv.js.org/)). This will then reject any invalid input, and display an error in the UI (or via a custom [onError](#onerror-function) function).
