For the record: The latter (fragments) is already possible. Default
values not, though.

You can say:

    def is-a-task($task, $priority, $descr)
        $task isa onto:task
        onto:priority: $priority
        onto:descr: $descr .

    finishing-ctm is-a-task(0.0001, "Not in the near future") .

Best regards,
