freedesktop - May 2010 - [fdo] sco keyboard resource on debian

I just sent this email to xdg but I'm not sure that was the right place?

How do I enable the sco keyboard resource? I am running Debian 5.  I
need to enable the scoansi function keys.  

[09:58:43] ~$ xterm -kt sco
KeyboardType resource "sco" not found

do I need to install anything?

Regards,
Bill
