Highlight Frontmatter in Markdown as YAML

[FichteFoll]

Markdown documents may occasionally have a so-called "frontmatter" that is frequently using YAML syntax.

Using an embed, highlighting of this should be trivial.

Before settling onto YAML, however, have you seen other kinds of frontmatter in Markdown documents and if yes, which syntax do they use and how are they separated from the body?

The only situation I saw frontmatter was with mdpopups, which uses YAML.

[FichteFoll]

Jekyll (and github issue templates) are other examples of YAML front matter.

I imagine most static page generators that allow for markdown input also chose to use YAML for front matter.
