For function arguments (actually for any SPARQL function), the trick is
to call the input variables ?arg1 so that they will be picked up
automatically. In other words, call the output variable of the previous
step ?arg1 (or use sml:CloneVariable to rename an existing variable) and
then leave the sp:arg1 in the function call empty.
