/**
 * @typedef Comment
 */

Actual error message from documentation lint:

/path/filename.js
        1:1  warning  Missing or invalid tag type
        1:1  warning  could not determine @name for hierarchy

The line number is wrong and there's no indication that the issue is with the @typedef. If lint wants to complain that @typedef should specify a type, a good error message would be:

/path/filename.js
        2:1  warning  @typedef without a type. Expected `@typedef <type> <namepath>`.

However, according to JSDoc docs, <type> is actually optional. So the fact that lint is even complaining might be a bug in documentationjs.
