It’s never required to use AX. Google doesn’t require it, neither does yahoo, or any other provider.
AX is an extension allowing you to fetch additional data, like user’s name, or email.
openid.ax.requiredcontains fields that you’d like to fetch and mark as required fields, that’s it.For more information, read the Attribute Exchange specification.
