 A @deftech{contract property} specifies the behavior of a structure when used as
-a contract.  It is specified in terms of seven accessors:
+a contract.  It is specified in terms of seven properties:

    of a contract violation;}

    contract (passed in the first argument) is stronger than some other
    contract (passed in the second argument) and whose default always
