import {Component,Directive} from 'angular2/core';
import {COMMON_DIRECTIVES} from 'angular2/common';
 
@Component({
  selector: '[icon]',directives: [COMMON_DIRECTIVES],template: `<svg role="img" class="o-icon o-icon--large">
                <use [xlink:href]="iconHref"></use>
              </svg>{{ innerText }}`
})
export class Icon {
  iconHref: string = 'icons/icons.svg#menu-dashboard';
  innerText: string = 'Dashboard';
}

这会触发错误：

EXCEPTION: Template parse errors:
  Can't bind to 'xlink:href' since it isn't a known native property ("<svg role="img" class="o-icon o-icon--large">
<use [ERROR ->][xlink:href]=iconHref></use>
  </svg>{{ innerText }}"): SvgIcon@1:21

如何设置动态xlink：href？
