How to specify arguments to a SWF loaded using a SWFLoader whose source was a ByteArray?

Question

When a path is specified as the source argument of a SWFLoader, arguments can be appended to the path so that the SWF runs with the desired arguments.

<mx:SWFLoader id="mySwf" source="pathOfSwf.swf?arg1=1"/>

How do you do the same thing when instead of a path you specify a ByteArray as the source argument of a SWFLoader.

<mx:SWFLoader id="mySwf" source="myByteArray"/>

Thanks!
