title: ng-bind : concatenate 2 values where one of them is conditional
body: <p>I am able to concatenate two values inside ng-bind by using '+'. However, the 2nd value depends on a condition.</p>
  
  <p>How can I hide/show this value using <strong>ng-if</strong> or <strong>ng-switch</strong>. I tried using ng-if but it ate the ng-bind (ie. interpolated values don't show at all. Maybe <strong>ng-if</strong> has greater priority as <strong>ng-bind</strong> has priority 0.  eg.</p>
  
  <p><code>&lt;a ng-bind="(document.name) + (vm.showifConditionTrue)"&gt;&lt;/a&gt;</code>  </p>
  
  <p>Thanks for any suggestion.</p>
