title: What are the Facebook app FBML 'profile.setFBML' arguments?
body: <p>Okay so I've read the documentation, and I'm not quite sure what the arguments being passed are. I'm looking at the the listed example request:</p>
  
  <p><code>$facebook->api_client->profile_setFBML(NULL, 128009, 'profile', NULL, 'mobile_profile', 'profile_main');</code></p>
  
  <p>and thinking, where are they getting these arguments and what do they do?</p>
  
  <p>Anybody have an explanation?</p>
