Oh, I think we should hide the Karajan interpolation from Swift.  I think 
the dataflow from string interpolation could be problematic.  My initial 
suggestion is to replace the generated <variable> elements with another 
element that skips interpolation, if that is in fact where this is coming 
from.  Or we could try to fix the original intended behavior.
