title: What are the InjectionMembers in RegisterType() calls for?
body: <p>I've been working with Microsoft's Unity IOC container. There are a bunch of overloads for the <code>RegisterType()</code> method all looking similar to</p>
  
  <pre><code>IUnityContainer RegisterType(Type t, params InjectionMember[] injectionMembers);
  </code></pre>
  
  <p>I'm wondering when the <code>injectionMembers</code> parameters are for? I couldn't find any documentation for the them (even though they're in every overload) and none of the sample code I looked at use them.</p>
  
  <p>Am I missing something here? Are they not commonly used or did I just miss the examples?</p>
