How to make Jade stop HTML encoding element attributes, and produce a literal string value?

Question

UPDATE Jade v0.24.0 fixes this with a != syntax for attributes. option(value!='<%= id %>')

---

I'm trying to build an <option> with jade, where the value of the option is an UnderscoreJS template marker: <%= id %> but I can't get it to work because jade is converting my marker text to <= id >.

Here's my Jade markup:

script(id="my-template", type="text/template")
  select(id="type")
    <% _.each(deviceTypes, function(type){ %>
    option(value='&lt;%= type.id %>') <%= type.name %>
    &lt;% }) %>

I expect it to produce this html:

<script id="my-template" type="text/template">
  <select id='type'>
    <% _.each(deviceTypes, function(type){ %>
    <option value="<%= type.id %>"> <%= type.name %> </option>
    <% }) %>
  </select>
</script>

But what I get instead, is this:

<script id="my-template" type="text/template">
  <select id='type'>
    <% _.each(deviceTypes, function(type){ %>
    <option value="&lt;%= type.id %&gt;"> <%= type.name %> </option>
    <% }) %>
  </select>
</script>

Note the very subtle difference in the <option> line of the output... the value attribute of the option has been HTML encoded.

How do I prevent Jade from HTML encoding this value? I need it to produce the literal value, the same way it does with the text of the option.

Derick has already mentioned that Jade added new feature for unescape HTML encoding in update, but I'd like to add some addendum for someone who might not recognize.

- var html = "<script></script>"
| !{html} <-- Escaped
| #{html} <-- Encoded
