Highlight markup syntax

[taronomy]

Hi, I’m working with a bunch of *.html.eex mostly greyed out on Zed.

EEx is versatile, but its syntax heavily implies markup.

<tag attr=“value”>hello</tag>
<%= if @a do %>world<% end %>
<!-- HTML/XML comment -->
<%!-- EEx comment  --%>

(I just realised GitHub highlights markup by default for EEx)

It would be beneficial if the EEx syntax highlights markup.

If HTML is too specific, XML-based would be good too.

Thanks!
