Here's mine:

(defconstant $keyAEContainer :|from|)
(defconstant $keyAEKeyForm :|form|)
(defconstant $keyAEKeyData :|seld|)

;;;create-obj-specifier duplicates the functionality of CreateObjSpecifier
;;;DisposeInputs is always false
(defun create-obj-specifier (desired-class container keyform keydatadesc

           (type desctype desired-class keyform))
