## What is this?

This is a map of tag names to lists of allowed attributes.
Global attributes are stored at the special tag name `*`.
All attributes from HTML 4 and the current living HTML spec are included.

> 👉 **Note**: Includes deprecated attributes.

> 👉 **Note**: Attributes which were not global in HTML 4 but are in HTML, are
> only included in the list of global attributes.

## When should I use this?

You can use this to figure out if certain attributes are allowed on certain
HTML elements.
