True, is_valid(A) isn't very useful in practise. But if all control
ports are guaranteed to be able to handle all possible values, you
can just use the default value range. If an invalid value is used,
the plugin just bypasses it. If needed, the host can afterwards check,
whether the given parameter value was valid.
