* `description`: A long description that can contain Markdown text.
* `value`: This is the actual example shown, e.g. a `dict`.
* `externalValue`: alternative to `value`, a URL pointing to the example. Although this might not be supported by as many tools as `value`.

You can use it like this:

## Переваги стандартів, альтернативна документація { #standards-based-benefits-alternative-documentation }

І оскільки згенерована схема відповідає стандарту [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md), існує багато сумісних інструментів.
