title: Boolean CommandParameter in XAML
body: <p>I have this code (which works just right):</p>
  
  <pre><code>&lt;KeyBinding Key="Enter" Command="{Binding ReturnResultCommand}"&gt;
      &lt;KeyBinding.CommandParameter&gt;
          &lt;s:Boolean&gt;
              True
          &lt;/s:Boolean&gt;
      &lt;/KeyBinding.CommandParameter&gt;
  &lt;/KeyBinding&gt;
  </code></pre>
  
  <p>Where "s" is of course the System namespace.</p>
  
  <p>But this command is called quite a few times and it really inflates otherwise rather simple XAML code. Is this really the shortest notation of boolean command parameter in XAML (other than splitting the command into several commands)?</p>
