WikiText can include blocks of text that are rendered with an explicit ContentType like this:

```
$$$application/javascript
//This is some JavaScript
var thing = 2 + "one";
$$$
```

This renders as:

$$$application/javascript
//This is some JavaScript
var thing = 2 + "one";
$$$

It is also possible to abbreviate the ContentType to a file extension. For example:

```
$$$.svg
<svg xmlns="http://www.w3.org/2000/svg" width="150" height="100">
  <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" />
</svg>
$$$
```

This renders as:

$$$.svg
<svg xmlns="http://www.w3.org/2000/svg" width="150" height="100">
  <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" />
</svg>
$$$

And, finally, a JSON example:

```
$$$.json
{"teapot": "brown","inside":["milk","sugar",23]}
$$$
```

Which renders as:

$$$.json
{"teapot": "brown","inside":["milk","sugar",23]}
$$$

Unknown types render as plain text:

```
$$$text/unknown
Some plain text, which will not be //formatted//.
$$$
```

Which renders as:

$$$text/unknown
Some plain text, which will not be //formatted//.
$$$

A render type can also be specified, causing a particular text rendering to be displayed. For example:

```
$$$text/vnd.tiddlywiki>text/html
This is ''some'' wikitext
$$$

$$$text/vnd.tiddlywiki>text/plain
This is ''some'' wikitext
$$$
```

Renders as:

$$$text/vnd.tiddlywiki>text/html
This is ''some'' wikitext
$$$

$$$text/vnd.tiddlywiki>text/plain
This is ''some'' wikitext
$$$
