* This is the response by the Reader to a STOP_ACCESSSPEC command. If the Reader was currently executing the AccessSpec corresponding to the AccessSpecID, and the Reader was able to disable that AccessSpec, then the success code is returned in the LLRPStatus parameter. If there is an error, the appropriate error code is returned in the LLRPStatus parameter.
