I'm not sure I'm following you.  What does "look it up internally" mean?

You could always write your task to take a String argument that 
represents the refid, and then look it up internally and deal with its 
potential non-existence yourself.

I'm not sure, without digging a bit, whether using a Reference type or 
not would do the trick, but it might.
