How do I reference linked movieclips in loaded SWFs?

Let’s say I have a movieclip in my SWF’s library, and its linkage is set to “MyClip” and it’s set to export.

I can add it to the stage by saying “addChild (new MyClip as MovieClip)”

Now let’s say I load a SWF as a loader object, and that loaded SWF has a similarly linked movieclip. How do I reference the linked movieclip in the loaded SWF?
