   VL, that effectively issues **multiple** identical instructions
   using contiguous sequentially-incrementing registers.
   **Whether they be executed sequentially or in parallel or a
-  mixture of both is entirely up to the implementor**.
+  mixture of both or punted to software-emulation in a trap handler

 In this way an entire scalar algorithm may be vectorised with
 the minimum of modification to the hardware and to compiler toolchains.
