title: flex 4: custom css value
body: <p>is there any way to create a custom css value for a component and have it available to the skin class that component is using? for example, if i define this in a css file:</p>
  
  <pre><code>s|Panel{
    skinClass: ClassReference("PanelSkin");
    myCustomValue: #CCCCFF;
  }
  </code></pre>
