The NgBindTemplateDirective specifies that the element text content should be replaced with the interpolation of the template in the ngBindTemplate attribute. Unlike ngBind, the ngBindTemplate can contain multiple {{ }} expressions.

@NgDirective(
 selector: '[ng-bind-template]',
 map: const {'ng-bind-template': '@bind'})
class NgBindTemplateDirective {
 dom.Element element;

 NgBindTemplateDirective(dom.Element this.element);

 set bind(value) {
   element.text = value;
 }
}
