How do I add a feature for recognizing 'frontmatter' metadata in Markdown and Markdown related documents?

It seems that Markdown is adding more missing features, in this case free-form metadata. I've been doing a fair bit of reading the last few days, and it seems that Markdown with 'frontmatter' has been gaining popularity.

Here is an established example: https://github.com/timlrx/tailwind-nextjs-starter-blog/blob/main/data/blog/code-sample.mdx

Here is a snippet:

---
author:
  - name one
  - name two
---
# Start Markdown

I would like to add recognition and handling for frontmatter in at least Markdown and ReStructuredText. How do I do this?

Pandoc has supported this since 2013; indeed, I think we were the first Markdown variant to support this style of metadata.

Can you help me with the documentation? I read over it, but it wasn't apparent to me which extensions need to be enabled.

It's enabled by default with -f markdown.

Thanks for humoring me. I was having some difficulty with the documentation and API last night.
