[`MarkSpec.toDOM()`](https://prosemirror.net/docs/ref/#model.MarkSpec.toDOM) accepts an `inline: boolean` argument. According to the documentation quoted below, it’s `true` in “_typical_” cases:
> `marks` does the same for mark names, but also gets an argument that tells it whether the mark’s content is block or inline content (for typical use, it’ll always be inline).
I would like to better understand the purpose of this argument, specifically the “_non-typical_” cases where `inline` would be false.
I have looked at the [original Git commit](https://github.com/ProseMirror/prosemirror-model/commit/df80581d6c62782ebb10a2380f50011c4f096b34) that added this argument, but I still do not understand. Is `inline` can ever be false at all?

It’s possible to allow marks on block nodes via the [`marks`](https://prosemirror.net/docs/ref/#model.NodeSpec.marks) setting in their parent nodes.
