      API-Link to the context in which the rendering occurs, for example a specific work package.

      If left out only context-agnostic rendering takes place.
      Please note that OpenProject features markdown-extensions on top of the extensions GitHub Flavored Markdown (gfm) already
      provides that can only work given a context (e.g. display attached images).

      **Supported contexts:**

      * `/api/v3/work_packages/{id}` - an existing work package
    example: "/api/v3/work_packages/42"
    in: query

        Returned if the context passed by the client is not valid (e.g. unknown).

        Note that this response will also occur when the requesting user
        is not allowed to see the context resource (e.g. limited work package visibility).
