<!-- language-all: lang-javascript -->

#### Test using `<!-- language: lang-none -->`  (i.e. should NOT have syntax highlighting)
Where indicated, the following sections are separately preceded by a line which contains `<!-- language: lang-none -->`, which should still prevent application of syntax highlighting. Note that using HTML comments to apply code formatting is deprecated.

##### In code fences

###### With `<!-- language: lang-none -->`
<!-- language: lang-none -->
```
var parent=document.getElementById('parent');
var child=document.getElementById('child');
var preventChild=document.getElementById('preventChild');
```
###### Without `<!-- language: lang-none -->`

```
var parent=document.getElementById('parent');
var child=document.getElementById('child');
var preventChild=document.getElementById('preventChild');
```

##### Using 4 space indent
###### With `<!-- language: lang-none -->`
<!-- language: lang-none -->

    var parent=document.getElementById('parent');
    var child=document.getElementById('child');
    var preventChild=document.getElementById('preventChild');
###### Without `<!-- language: lang-none -->`

    var parent=document.getElementById('parent');
    var child=document.getElementById('child');
    var preventChild=document.getElementById('preventChild');



##### In HTML `<pre><code>`
###### With `<!-- language: lang-none -->`
<!-- language: lang-none -->

<pre><code>var parent=document.getElementById('parent');
var child=document.getElementById('child');
var preventChild=document.getElementById('preventChild');
</pre></code>
###### Without `<!-- language: lang-none -->`

<pre><code>var parent=document.getElementById('parent');
var child=document.getElementById('child');
var preventChild=document.getElementById('preventChild');
</pre></code>

All of the above function as expected in the preview below the text input while editing.
