## What is this?

This is a list of HTML tag names.
It includes ancient (for example, `nextid` and `basefont`) and modern (for
example, `shadow` and `template`) names from the HTML living standard.
The repo includes scripts to regenerate the data from the specs.

## When should I use this?

You can use this package when you need to know what tag names are allowed in
any version of HTML.
