-Whenever configuration elements are added or updated, the document definitions schema (see the `src/validation/document-definition-schema` and `src/validation/property-validator-schema` modules) must also be updated for use by the document-definitions-validator module. The schema is defined according to the [Joi](https://github.com/hapijs/joi) library's API.
