Display a 'credit card' form

After receiving a response from the government server, look up the requested form. Use that form configuration to generate an HTML page to display to the user's browser.

The form can be configured with hidden fields, editable fields, or "locked" fields (visible but not editable without modifying the markup). It does not submit anywhere -- the next step is to send the results back to the government server.
Is this a real URL? Should we using a fake one?
