The Markdown parsing library I'm using supports MDX, so it shouldn't be too difficult to come up with syntax for those components. I haven't done that yet, but mostly because I didn't want to go down that path until I knew there was interest and had a concrete use case or two to inform the query syntax.

If you want to open an enhancement request issue, I'm happy to take a look (PRs also welcome, but not required). If you're not on GitHub, let me know and we can figure out some other way to get the request tracked.

Thanks for taking a look at the project!
