A "raw attribute" is an =
plus an alphanumeric string, in
braces, like
{=html5}
If attached to an inline code span, it causes the span to be interpreted as raw inline content with the specified format. If attached to a fenced code block, it causes the block to be interpreted as raw block content with the specified format. A raw attribute may not occur together with other attributes.
``` {=html}
<b>foo</b>
```
.
<b>foo</b>
`<b>foo</b>`{=html}
.
<p><b>foo</b></p>
You can't mix regular and raw attributes:
``` {=html #id}
<b>foo</b>
.
<pre><code class="language-{=html"><b>foo</b>
</code></pre>
`<b>foo</b>`{=html .bar}
.
<p><code><b>foo</b></code>{=html .bar}</p>
