I'm referring to the thread that has been created earlier...

Customer is using the IDM 3.5 create portlet to allow a user to
self-register,
and require them to enter a telephone number.

Is there a way to set up validation on this field through the create
portlet? In the Directory Access Layer we have specified a Format Type of
Phone Number, but this does not appear to force an field validation; for
example, I can enter "abcd" in the phone number field and it is accepted.

Thanks for any help!
