This follows the exact same pattern used for all other item attributes (like `item_categories`, `item_copyright`, `item_guid`, etc.).\n\nNow users can define `item_comments` on their `Feed` subclass (either as an attribute or a method taking an item) and it will be passed through to the feed generator's `add_item()` method, which already supports the `comments` parameter and renders it in RSS output as a `<comments>` element.",
