No, CCK does not.
However, FAPI does. :-) You can use hook_form_alter() in your own module somewhere to add another validation function to the form. In that validation function, just set a form error if you don't like what the user's doing. FAPI will take care of rejecting the form and showing it back to the user with your message. That the form is built with CCK is irrelevant to this task.
Cheers.

hey there -
I'm looking to use CCK fields for defining if an article is exclusive to a role of users along with a specified timeframe.
Is it possible to utilize some sort of validation whereby if a role is specified then a startdate and enddate must be specified?
The trick is that if they specify a role, I need them to also specify a startdate and enddate.
Does the CCK module allow for hooks to alter the form and/or specify more advanced validation rules?
i've read about node_alter_form and hook_alter_form, but how does one use them with CCK fields?
Any advice would be greatly appreciated.
