How to add description to array items?

[risabhds]

I want to generate the following json schema:

{
    "$schema": "https://json-schema.org/draft/2020-12/schema",
    "$id": "Demo.json",
    "type": "object",
    "properties": {
        "example": {
            "type": "array",
            "items": {
                "type": "string",
                "description": "some description of string"
            }
        }
    },
    "required": [
        "example"
    ]
}

Notice the description is with type: string and not type: array.

But unable to get this using typespec. The description is added on type: array.

It is not possible as it is, if you do need that the solution is to create an array model with the description

model Demo {
  example: ArrayOfString;
}

/** some description of string */
model ArrayOfString is string[];

Thanks for the response! I ended up doing the same but was still curious if there was a way to do this without creating a new model.
