How to provide Return URL Verification with OpenID?

Question

I am using the PHP OpenID library from http://openidenabled.com on my site. However, I just realised I need to support Return URL Verification. How can I do that with this class? I paged through the docs but I couldn't find anything.

Edit: forgot to mention it is a CONSUMER application.
