You can place some fields that are actually not in the model in the
validate array. The problem with your case, it that you do not have a
definite limit.
There is an option you can set in the $validate .. 'on' => 'create'
and 'on' => 'update' associated with the array (same level as 'rule').
I have seen it in the code of validation.php in the cake1.2 branch and
it relies on the definition of $id in the $this->data of the
Model ..maybe it's on way (but really never tried it)...
