Can a Silverlight 5 assembly reference a Silverlight 4 assembly?

Question

Is a Silverlight 4 assembly binary compatible with Silverlight 5. Is a SL4 assembly "run in the SL5 runtime"? If it is compatible, is it 100% compatible. You should be able to use a 3rd party SL4 assembly in your SL5 project?

Or is it more like .NET framework 2 and .NET framework 4, that runs side by side?

If I remember correctly SL2 and SL3 was not compatible.
