HTML supports unquoted attributes, we use a template language that uses unquoted attributes for templating and requires template attributes to NOT have templates. It would be ideal to support an option to not surround attributes with quotes.

Alternatively, having a "sub" HTML syntax like is done with Vue would work as well. We'd prefer to avoid forking the entire HTML plugin just to change this single format if possible.

--parser html

Input:

<div>
  <p id={VALUE}>Hello</p>
</div>

Output:

<div><p id="{VALUE}">Hello</p></div>

Expected behavior:
The attribute should not be surrounded by quotes.

<div><p id={VALUE}>Hello</p></div>
