This mentions that its doable to customize public registration fields but, doesn't indicate how.
Check [this](http://www.gluu.org/docs/admin-guide/user-management/registration/) doc. If you "enable" *Configure registration From Attribute*, it will help you to select which attributes should be in registration page and which are not.
