Fb:serverfbml
From Facebook Developer Wiki

Description
Renders the FBML on a Facebook server inside an iframe. You must use this tag to render elements on Facebook like fb:request-form and fb:connect-form (for friend selectors). The tags that don't need to be used with fb:serverfbml are listed on the XFBML page.
This container tag holds display/FBML elements that must be served in a Facebook iframe for security reasons. For instance, the fb:request-form tag must be wrapped inside this tag in order to work on a Facebook Connect site, since we need to be able to verify that the user performed the actions on the form.

Notes
Using the condition Attribute
All XFBML tags support the condition attribute. This attribute determines whether an XFBML element is visible or hidden. When condition is absent, the element is visible by default. The value of condition should be a string containing some JavaScript code. The JavaScript should be evaluated into either a boolean or an FB.Waitable object whose result field is a boolean. The FB.Waitable object is designed to allow asynchronous evaluation. For example, if you want to specify an element should be visible only if the current users can see the profile of another user, you can use this markup:
The following are some pre-built condition objects.
