The following YAML file is a basic (slightly simplified and opinionated) representation of the HTML5 specifications.
I’m not sure if this is useful to anyone, but hey… you have found this page.
My specific use-case for an HTML5 specification was code-generation. I use it to generate Storybook stories for each and every HTML5 element and to use some Faker to pre-populate content.
