Specifies that a constant attribute value should be injected.
The directive can inject constant string literals of host element attributes.
## Example
Suppose we have an `<input>` element and want to know its `type`.
```html
<input type="text">
```
A decorator can inject string literal `text` like so:
```javascript
@Decorator({
selector: `input'
})
class InputDecorator {
constructor(@Attribute('type') type) {
// type would be `text` in this example
}
}
