This doesnt feel right.

The code would need to validate the actual value the same way it
checks min/max at least

avoptions allows the user to obtain a parameters address and set
it directly as well as set it without any AVOption

iam still not sure thats a good idea.
Why are the values not in a continous sequence of integers that can
be checked with min/max ?

thx
