 // |profile| is profile from which you can get vectors of of autofill profiles
 // that contains the current profile information and credit cards.
 // The dialog fills out the profile fields using this data. |observer| will be
 // notified by OnAutoFillDialogAccept when the user has applied changes.
 //
+// The |parent| parameter (currently only used on Windows) specifies the parent
+// view in the view hierarchy.  May be NULL on Mac and gtk.

+// supplied.  If they are supplied (non-NULL) they will be used instead of
+// the profile and credit card data retrieved from the PersonalDataManager
+// associated with the |profile|.
+//
 // The PersonalDataManager owns the contents of these vectors.  The lifetime of
 // the contents is until the PersonalDataManager replaces them with new data
 // whenever the web database is updated.
