title: Knockout.js "if Binding" on multiple booleans
body: <p>Is it possible to use Knockout's <strong><a href="http://knockoutjs.com/documentation/if-binding.html">if binding</a></strong> on more than one boolean?</p>
  
  <p>Such as</p>
  
  <pre><code>&lt;div data-bind="if: (property.aTrueValue &amp;&amp; property.anotherTrueValue)"&gt;...
  </code></pre>
  
  <p>I've tried a lot of different syntax, but can't seem to find the right syntax.
  I'm not sure it's even possible.</p>
