Is it possible to let ProseMirror to output XHTML? I’ve looked at one of the introductory examples and there I see `<hr>`. I’m wondering whether I can make this a self closing tag: `<hr/>`

The `DOMSerializer` outputs a DOM tree, not HTML. It shouldn’t be too hard to run a function over that that produces an XHTML string.

Thanks for the follow up. Let me also check tiptap which I believe have a dedicated function for that.
