customize /identity/firstlogin page

Hey guyz,

Has anybody tried to perform any customization to this page?

1) I tried but it seems like all what I can do is just show/hide some elements. When I try to add anything, I get back a message that I do not have access to it

2) If i try to export, change, import a sandbox, OIM doesn't show the page at all. Below is my customization code

<?xml version='1.0' encoding='UTF-8'?>
