Title: Attributes content should be "unescaped", because browser engines escape...

... them automatically.

Take for example (inspired by real case of Google AdSense):

```javascript
document.write('');
```

The attribute value parsed from raw string is `foo&&bar` and that would be passed to `el.setAttribute()`, but the real value is `foo&&bar` and browser will take care for escaping it on it's own.
