In our scheme interppreter we have an additional value, #<unspecified>,
that we use for cases where IEEE R4RS doesn't say what should happen in
some specific case, or says explicitly that a particular result is unspeified:
    : sqrex!lee; sqpsi
    > (define (x y) (+ y 6))

As far as I can see, a DSSSL implementation could also do this if it wanted.
I don't have the DSSSL spec in front of me here in New York to investigate
this further.
