No Validation on Registration Page

Hi

On registration page, I need to have company registration number which is 14 digits.
I have created an Xprofile field.
– type Numeric
– Character limit 14
– minimum characters 14

Validation works when editing a profile but the validation does not work on registration page.

Any update planned for this plugin ?
This is a great plugin, the only one I found with such features ; I hope this plugin will keep on being updated.

Thanks

Regards

Johan
