OK, talked over with Jiwon and the room here at the sprint and the
preference was to keep it as-is.  Reasons were it allowed the position in
the signature to be kept with the object (and thus not be reliant on the
Signature object to know its position in the actual output), and the
possibility of disparate types being in the attribute.  Plus Guido preferred
the original way.  =)
