[plt-scheme] r6rs mode, empty nongenerative forms

  it seems to  me that PLT version 4.2.4  does not allow the
NONGENERATIVE auxiliary syntax to  be used without value, as

  (define-record-type (:sentinel make-sentinel sentinel?)
    (opaque #t)
    (sealed #t)

while  R6RS states  that this  is  possible and  the uid  is
automatically  generated at  expansion time.   I do  not see
this incompatibility listed at


can it be added?
