@aslakr As far as I know, there's no such thing. 🤔

@hongminhee Maybe activitypub implementations like Mastodon should not filter out https://html.spec.whatwg.org/multipage/microdata.html like `itemscope`, `itemtype` etc.?

One could then use something like https://schema.org/SoftwareSourceCode indicating that there is a source code block that could be highlighted for the user.
