  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
  @Directive({
    selector: `input'
  })
  class InputDirective {
    constructor(@Attribute('type') type) {
      // type would be `text` in this example
    }
  }
  ```
